Attached to a scroll saw you can cut nested wooden spirals with this jig. Make two, three, four ... interlocking spirals that unwind/unscrew. Fascinating toys or art objects!

I am currently 15 years old, from Germany and trying to build a low budged CNC router. I only designed this CNC based on other CNC routers that I have seen and what I am able of. It consists mostly of 2.3cm plywood to keep costs down. The size of the work area is approx. 40 x 80 cm. I would be really glad if you could give me advice's for improvement on the design and everything else ... ( I could really need your help :) ) enjoy :)

This project is focused on developing a low-cost, portable and open-source FDM 3D Printer.
