This is a mostly 3D printed electric winch that I build to pull myself up a climbing wall like a rope ascender.

This is a electric winch that uses 2 775 dc motors with about 1 to 131 gear reduction. This is strong enough that it can pull me straight up.
Here is the video that includes design decisions, necessary calculations, design build and testing.
Since the gears are completely open, this project is dangerous the final drive is really high and can really hurt someone, build and play with it at your own safety.
For build instructions here is the instructables link, with the video this should be enough feel free to message me if it's not:
For the motor mounts I was afraid they would give way as the motors heat up and also to help keep the motors cool I used JLCCNC to machine them.
