Summary

This is the Mantis 9.1 designed by David Carr at MIT. It is a mini mill that people have built for less than 100 dollars. It seems to be best at pcb engraving and other semi hard materials.

Here are a set of videos That David posted. I reccommend watching all of them before starting. I did make 1 change: I changed the "tap yourself" acme nuts to a McMaster steel nut. I did use a cheap part. I did this because the ACME tap kit I found for this cost around 200 dollars. I'm looking forward to seeing what other people do with this design. I will be building it at FabLab Tulsa.

I'll keep adding files as I make more progress. Feel free to request things, I hope I can help.
