I had to make one: https://www.thingiverse.com/thing:2094215. Projection is shorter range than I was hoping for but it’s still fun and gets the kids thinking.
SketchyBot 1.0
I finally built a standard sized one. I ran into a few unexpected challenges given how smooth the small one went.
It really isn’t the most accurate machine, the belts inside aren’t timed, but it does pretty ok with some rendering algorithm and is fun.
PewtyBot 1.0 x2
I built another one, it’s always been useful to have 2 of my drawing machines.
