Shaft hole drilling jig

This jig allows you to drill holes through the center of shafts, which I use primarily to attach gears and shaft collars. The jig in the .stl files is for shafts 6-12mm in diameter, and with a hole diameter of 4mm. You will need to find a long drill bushing. For other shaft/hole sizes you can modify the fusion360 file included. If you need help with that let me know.
