For E’s birthday two months ago I made him a laser cut spirograph. It works pretty well and I really enjoyed making it! I tried downloading some existing plans for them, but they didn’t mesh well. I ended up using Inkscape to draw the gears. That tutorial makes them look pretty for an illustration, but they’re real gears and the mesh well! Not perfect, but well enough. For the case I started with a basic box-joint box from the ever awesome MakerCase, and then used Inkscape to add the florishes.
If you want to make one yourself, here’s the .svg of the two inner and outer gears. If you want to make the case, here’s the .svg for that too.
Otherwise, enjoy the fabrication and final product pictures:
