Don’t let your wards grow up to be junkies

Modeling a 3D-printed boxing glove arrowhead in around 20 easy steps.

6:29 AM Start with a cube. Riveting.

glove_001

Subdivide the cube and scale it in Y.

glove_002

Pull some points until the cube has the rough shape of a hand.

glove_003

Do a test smoothing to see if the basic shape is going to work out. Looks good.

glove_004

Go back to the low-resolution form and add a cube for a thumb.

glove_005

6:44 AM Scale the thumb and add a little detail at the tip and a knuckle joint.

glove_006

Boolean join the two forms. This is going to create some weird geometry at the thumb/hand junction. I wouldn’t do this if I was modeling for a video game, but it’s OK here since I’m not going to deform the model much. It bugs me on an aesthetic level, but I want to get this done fast and not worry too much about immaculate topology.

glove_007

Add a beveled cube for the wrist.

glove_008

Smooth the cube a bit and squish the insides in with a lattice deformer. I haven’t actually booleaned the wrist to the hand yet. Smooth the hand and use the Sculpt Geometry tool to further smooth out some sharp edges.

glove_011

Create a cylinder to punch out the arrow socket. Again, from a video game modeling perspective, this geometry is an absolute mess. It’ll print fine though.

glove_012

Test print! Looks pretty good, but it’s a little stiff. Back to Maya.

test_print

Deform the entire glove with a lattice to give it a little cartoony character.

glove_013

Uh oh. The arrow socket got deformed when I twisted the glove. Easy fix though. I wanted to make the socket just a wee bit larger anyway so the arrow was easier to remove.

glove_014

7:00: Breakfast break. Did some other things until 8:20 or so.

8:24 AM: A final once-over with the sculpting tools to introduce a little randomness in the geometry.

glove_015

Final print in red ABS, because (red funny > white funny.)

glove_with_arrows

Designed to fit these arrows, but will probably fit a pencil too.
