CNC Adapter

With this adapter you can transform your 3D printer into a CNC: it allows you to install a 300W engraving DC spindle (52mm dia) onto a base plate that has 50mm center-to-center M4 holes. These CNC spindles are common on eBay and typically come with an ER11 collet and weigh around 800 grams (a bit more than two extruders).
