Switching gears.

So I’ve been cranking out Seej models for a couple of weeks and I decided to take a little break and work on something else.

I’m standing on the giant shoulders of Leemon Baird for his work on the Public Domain Involute Parametric Gear Set– without his contribution, I wouldn’t have been able to create the Tinkeriffic Gear Train.

This was my first experience with OpenSCAD. It’s tremendously powerful at the expense of simple interface. I know half a dozen programmers who would really enjoy working with it, and twice as many artists who would run away screaming.

I cranked out a couple of basic gears, imported them into Maya, and then hit the “make it better” button a couple of dozen times to get this final result:

I’ve been reading up on woodworking techniques, trying to find methods of fitting 3D printed plastic parts together without adhesives.

I settled on dovetails for the rack gears. This way people can print male, female, and male/female racks and link them together in as long a sequence as they like.

If you’re feeling nostalgic and don’t have an old Tinkertoy set in the basement, you can go grab a Tinkertoy Classic Jumbo Set to use with these gears.

What do you think?
