Gemfan DJI to 5mm Prop Adapter

Remixed prop adapter to specifically fit Gemfan 1045 DJI props and convert them to a 5mm diameter motor shaft.

I've also included a version which has a narrower hole at the top, allowing for the threaded top section of the motor shaft to be slightly narrower than the un-threaded bottom section, and put a slight taper at the transition. This makes for a better fit.

OpenSCAD files included so the adapter can be altered as needed for other props or fitments.
