Drill bit sharpener for "generic" rotary tool
thingiverse
I redesigned the drill bit sharpener from pscrespo's remix of MGX's design to fit a Chinese rotary tool with a 16.8mm external diameter thread. The low cost of this rotary tool makes it widely available, but its accessory attachment thread is smaller than that of the Dremel. For instructions on assembly and usage, see the description of MGX sharpener. Print Settings: Printer Brand: Prusa Printer Model: Prusa Steel Rafts: No Supports: Yes Resolution: 0.4mm hotend with a 0.1mm layer height Infill Percentage: 40% Design Process: I used FreeCad to edit the original STL file, adding a new thread that allows it to be attached to the Chinese rotary tool.
