Business Card Holder 3D Modeling with Rhino 6 (2018)


Many of you requests to do a tutorial
for everyday objects, so I decided to make this business card holder. It’s been
print and test, and it’s working very well, so we’re gonna talk about a model today and
also I have a secret bonus for you. so stay tuned till the end of the video.
Let’s get started! to create a business card holder, we need to know what is the
standard size for a business card. so if you go to Google. Type in business card
size. It’s gonna give you the standard size for 3.5 x 2 inch, so I draw a box here
to represent a business card. This is in the mm, and then I will go to the
box and I’ve tried to creating a box right here follow this dimension
right there. My business card is 0.4 millimeter which means, if I want to have
10 business card I need to have about 4 millimeters space there, and if you
like to make your business card holder holding a lot more, you just need to
adjust the high okay, so now we have this business card holder there. I want to
move it to the center, so instead of… we can do is, I know this is a 4
millimeter, I can move it down 2. That is one way to do it.
sorry that I need to do the -2 so that’s one way to do it. Another way
we can do is let’s go back. we can always use the align tool. I use align
tool all the time. It’s really convenient so we’re gonna go to align tool, align
to the center, and just need to type 0, so it doesn’t matter how thick that is. They
were going to right in the middle of the line to the center. Alright so now we
have this business card. All we need to do is we need to make it slightly bigger.
the reason is that I don’t want my business card jamming inside of the
holder, so I want to give it a little bit more room like that. Alright so that is
roughly about 1 millimeter all the way, you don’t need to have that big maybe I
was just scale just a little bit back. alright also we have a little
bit room there, so it’s not that jam-packed. So you can see that was
original size, and we want to use this box as our reference. Since it’s a
reference, I’m going to lock both of them so I won’t accidentally to click it, and I
gonna delete this dimension here. Let’s take a look the business card holder
that I have previously. As you can see I have the car holder is all the way
round it, if you have a box, and you fillet the edges, and it’s gonna be really boxy
looking, so I want to create this like really pillow looking outline there. So
what I’m going to do is I’m gonna turn this off. I’m going to create some
reference lines for us. So first, I’m gonna snap to the zero point with the
straight line, and it’s gonna have it coming up for any of the
lengths that you possibly going to build. so I’m gonna have this business call
between 1.5 to 2 mm then I’m going to put the
tab there okay so that’s exploded that’s all right. The next things I
wanted to do is I need to creating a outline for what that is. So I’m gonna do is
to go into a rectangle tool, and you right-click on the very last one with
the conic corner, and you want to snapping into the zero for the center. then I wanna coming out here, and then to do a proper size.
You don’t need to have it super thick. We want to be easy to carry, so I’m gonna do
something like this. I enlarge to the top view, and then you can coming in
like this, so this is my business card let me move to the left a little bit,
and see if that work really well. The reason is like that is later on I’m going to cut a
hole out there. but am I gonna move it back from
now is easy for us to do everything right in the center. so I gotta make it
just a little bit longer, and maybe a little bit wider. too. Because that corner
is really close, okay so now we have this, we wanna design a shell for it, so I’m
going to snapping into this endpoint that’s going to the right view, and I
gonna put the tab there alright. so this is going to help us to have a really
nice curves for blend. So let’s go to the blend tool, and we’re gonna blend
from this little tab, they’re going to this little tab there, so now you have
really nice curve, but it’s bumpy at the end, so I’m gonna move in this down like
this, and it’s better to see the front view or on the side view, so that way you
can see how well that you have this curve there. I can move in this one there.
so it’s a nice curve there, and I click OK on it. so now we have this curve and
since we want to make it into the solid. Let’s go ahead to me mirror that to the
other side, and join it okay. so now we have the curve, we have the rail, and we
are going to use the commend under the surface and this is called Rail revolve.
so first of all you will be asked to choose the profile, so this is our
profile. this is the rail, and we are going to do from this end to this end, so
now I got very nice shell for it. and after we do that, I’m going to move
it to the left size a little bit. The reason I do that, again, I want to cut out
the opening there, so this is like this one, so I can put the
strap there to holding with my ID at the same time. Alright. The second things I wanted to do is I need to cut an opening, so that’s
going to the front view. At the front view, I
wanted to slide a opening there, so I might wanted to cut something
like this. alright and then with that cutting, I
need to have a close curve, so I can creating a solid, so I’m gonna join those
two. Now let’s take a look on the whole view. A lot of times you have
something like this. It’s because Osnap is on, and it’s kind of snap
everywhere, so a lot of times they are not flat. To solve this issue, just go to
the front view and we want to type it “ProjectToCplane” and we want to
delete the input so now we have it flat straight right there.
okay that’s go ahead using the solid- extrude a plane- straight, and then
we have in this one make sure the solid=YES so we’re gonna do the
boolean difference, we cannot do difference from this one out of this one.
so now we got a solid piece right there. We also is going to cut the space
out, so I’m going to unlock that guy and then I’m gonna use boolean difference
again, so this one will be boolean out of this one, so now we have a box there okay
so the box is done. then next one, we need to do the pattern on the top. so I
need to know where is this the space I’m going to do the design. I’m gonna use
this one the curve that I have because that’s fitting into the profile, and let
me have those two… actually have everybody. and align to the center,
and type in zero there. okay we don’t need this, I’m going to hide this one,
alright so now we have this box right there, I’m gonna use the curve tool, and
just kind of scale it down to find what is the good design area right there.
before we are doing any design would like to have an opening right at
this area, so that way I can have the thumb to slice the business card out.
Let’s go to the square rectangular tool and I wanted to have conic corner, so
now I’m going to snap to the midpoint with the center of the rectangle, and I
can decide it like how big I wanted to this space to have, and have like really
nice round edges, also notice that we don’t want to cut it into the box, where
this area is. We want just cutting inside of it, so I’m gonna have a curve and pick
up both of them, and I’m going to split I’m sorry trim this one to this one, and
then make sure that they are touching. now it’s not touching
so I need to move this curve, gonna move it from the end point to this end point.
and then join those two curves. Now they are joined. Let’s go ahead to solid-
extrude a planar curve- straight, so then we will have this as our cutting tool.
Just want to slightly move up a little bit, so it’s not cutting into the bottom
of the box, and let’s use the boolean different, so now we have this open so
it’s pretty much we get basic of everything that we have. We also want to cut an
opening right there, so I’m gonna use the conic rectangular again, and we want to
snapping into any of the point right there with the center. Don’t forget to
click on the center and then it can be any size that you want depends on
how thick your strap is going to have go through that area, and then let’s do
the solid- extrude a planar curve- it kind of see me doing a repeating command that
that’s helping you to memorize this command much easier, so we’re gonna do
the boolean difference. so now we have this out of this, so this is what we get
there so let’s do some pattern design here on
the top space right here, so let’s go ahead and make sure the grid snip is on.
and we want to turn on this right there. and also want to draw a circle right in
the middle. You can create any pattern you like. I just like to have some
geometric shape, and then now I’m going to draw another rectangle
there. Alright so with all of this, I’m going to use the trim tool to trim
anywhere that I don’t need. Something like this right there, and you
guys so now I have this pattern right there. I’m going to join it while I
select all of them, so now this pattern need to flow into it. Apparently this guy
is a little bit too big, but that’s okay we’re gonna scale it down later on so
let me group this guy first. I’m gonna using the array tool that you have this
rectangular array. We’re gonna go… depends on how many you
need it, and since I don’t know I’m just gonna use more than what I need. I’m
gonna have 15 here, the y-axis is a little bit shorter, so I cannot do 10 here.
And then Z, I don’t need… I just need 1 So that’s hit ENTER, then you were
asked what space do you need it, so I want to keep it like 2 mm
here that I have like that so this is gonna be my pattern and after I
do that, I wanted to select all of them and kind of scale into the size that may
fit into my design right there. so I’m going to move it roughly here and see
which one may work, within that that design area right there.
another thing is I may want to group them temporary, and then also I
wanted to move it to somewhere can align to the center, so I’m gonna pick up my
object, and all those pattern. I’m gonna use the
align Center, and type is zero, so that way they will be right in the center.
okay so now I can use… selected object, I can use my Gumball to move them
to the area that I like. You can get rid of the grid snap, so you can move
it a little bit closer or something like this. okay so now we have everything in the right place, let’s just go ahead to
ungroup this one, and delete anything outside of that design area, so I’ll do
something maybe individual of them, I need to delete it more, so let’s do
this first Let’s delete those guy right there.
Alright and follow individual of them, I need to ungroup one more time, so I can
delete this way, okay and right there hanging over there we want to keep
everything in the design area, so we probably want to delete those and
couple of this guy where is sticking into the corner, that may not be
too good, and then of course this open area, we need to delete bunch of it, so
that stated somewhere there, and again this is just happen to the pattern that
I like, and it worked out pretty good on my print, so you can design whatever area
that whatever patterns I work for you. okay so now you’d like everything let’s
go ahead to select all those pattern, Let’s group it again, so we don’t have
to select individually. Let’s take a look. So that it looks good, and I’m
going to solid- extrude planner curve-straight and I’m going to straighten them up a
little bit like this. okay so now you have this pattern it’s ready that’s
going to do the boolean difference. Let’s start drawing the area for the
clip go to a rectangle tool- conic corner. make sure centers its click, and
then we want to do it I mean it’s up to you like how big that clip is going to
be but it doesn’t have to be super big okay so I’m gonna move it right there a
little bit, so now I have this. This is actually it’s gonna be in the back, so
it’s easier to see like this. alright so beside the opening we also
need to design an area. It’s kind of going in so I’m gonna turn off the rest
of it and just walking on this area right there. Okay I’m going to make a
copy, CTRL C, CTRL V, and scale one of it coming down, and also want to move it a
little bit right there. You can design every there depends on how you
like for those opening, but you don’t want to be open too much, you want to
keep it this as a big piece, so when you are printing I still have enough
material to hold the tension, so now we need to go on the front view.
Before I do that, I want to put a dot (point) there, so I can see the front view, to see
where’s the ending. okay so now let’s go to the front view, okay so we want to
clip look like this, we wanted to coming up there, Let’s take a look at our model
first. Alright so we wanted to come up somewhere from here and coming
back here, and then snapping into our outline there. so let me smart track here,
so that’s where we wanted to end it, so this is what the clip should look like. I
may want to have this one coming back a little bit so that’s easier for my car
to slicing without catching any end of it. so let me move this guy, move
this guy, and coming back a little bit, so it’s a nice curve over there. Alright
so what we going to do with this is let’s go back to perspective. Now we have
something like this. All we need to do is using the command is under the curve or
you can look for the icon here is the “curve from 2 views”, so I’m gonna click on
this one, and this one, and that give me a very interesting….I think
I’m upside down, yeah okay, so let’s take a look our model. It is sitting inside of it
really nice, okay alright, so what we need to do is we need to create a thickness
of this guy, so to do that we can use the curve that we have, and then extrude
straight on the both side. and using this curve to trim the extra
off, so now we have a surface like that, now what we like to do is cut the
opening to the back. so I’m gonna use this curve, and then I’m gonna go
through the solid-extrude planar curve- straight. We need a solid piece there.
We don’t need both sides, we just need one side, and we want to go in inside of
that piece there. So let’s go ahead to cut this open, so boolean difference, this
guy will be out of our cutting red color tool, so now I have this opening there
okay now what we need to do is to creating the thickness of this red
surface that we have. so I’m gonna come in here, and then I’m going to creating a
thickness by going to the solid- extruded surface. so we want to extrude a surface
straight. The thickness is gonna go from there to there. Alright so now we have
this piece right there. so let’s double check with four
view right there, so you want to make sure the tongue is not touching the part
are you going to print, otherwise your business car won’t slide in there, and
you may also need to adjust the high. this might be a little bit too tight, but
this for the demonstration. I’m just gonna leave it there, so this is what we
have for the business car, and I will suggest you to fillet all the
way, so ensure that it’s not scratching your business card and it is nice and smooth and
then that will be the demo today. At the beginning of tutorial, I promise you there
will be bonus, I’m actually giving out this model in STL file. This has been
print and test. And all the edges has been nicely smooth out, I also test the
tension it works really nice, so I’m giving out this file. All you need to do
is sign up my email list at the link below. I promise I won’t send you
junk. Only the good stuff and my modeling secrets. So sign up the link below and get
