Spirograph machine

It is my design for a spirograph machine.

It is 3d printed except for an M2 nut and bolt to fix a pen to the handler.

All the pieces can be printed at 0.32 except the nuts and bolts. I recommend changing the resolution to 0.2 at least for the bolt areas and 0.16 for the nuts.

You can save printing time and money printing some pieces without the bottom and top layers like me.
