A little bot based on the egg-bot to draw on a etch-a-sketch. You can now be an etch-a-sketch master too.

Etch-a-sketch doesn't do circles very well, so it works better if you create a series of straight lines.

Print out the STL.

You will need about a foot of 5/16" all-thread, and 4x 5/16" nuts, which you can get from the hardware store.

There are 4 x 3M nut traps for 4 set screws.

Play with the egg-bot software to draw stuff.
