Proxxon Rotary Tool IBS/E dust shoe CNC spindle using a 20mm Motor Mount

thingiverse

A custom motor adapter for CNC machine enthusiasts designed to convert Proxxon rotary tools into a spindle system, optimized for use with the Shapeoko CNC. The provided 20mm motor mount, typically known as an ID20mm Spindle Motor Mount Proxxon IB/E 50/E, enables users to efficiently power their CNC setup. Users are invited to explore an updated version of this project at http://www.thingiverse.com/thing:724287. This revised iteration streamlines the design by replacing traditional screw mounts with easy-to-install bungee cords, simplifying the process of tool changes and providing better clearance for clamps or other hold-down tools. Instructions are as follows: When assembling the threaded coupler, note that it can be somewhat stiff due to tight tolerances. Users are advised to thoroughly clean the thread after printing and apply gentle torque until the parts snugly fit together without air gaps. Important assembly steps include rotating the coupler and spindle mount by 180 degrees, while ensuring the base remains undisturbed, before commencing the printing process. Printing these parts upside down can yield optimal results due to their unique geometry.
