I originally made this for my TackLife rotary tool. I also included a test file so that you can try it on your specific model and test the fit before printing the actual adapter.
The adapter is longer than the thread on the rotary tool in order to increase the grip of the drill press squareness of the assembly.
The print itself is quite fast. It should be printed completely solid, so use at least 4 or 5 walls in order to avoid infill near the threads.
The author marked this model as their own original creation.
