Satsuma 180 v1.0

Project is no longer under active development or maintenance by me. Feel free to remix or reuse.

Welcome to project Satsuma  : )

This project uses SOME of the Prusa mini + additional components to make a CoreXY Printer. Keeping with the design decisions of the Prusa mini I have used square nuts M3, M5 instead of heat-set inserts, making assembly a breeze.

(DO NOT DESTROY YOUR WORKING PRUSA MINI TO MAKE THIS PRINTER Source the parts elsewhere)
