Rope Loop Handle

A handle with a 6mm groove to make pulling a rope tied in a loop more comfortable by hand.
Max hand width that can fit inside is about 100mm.

Easiest way to print this is groove down, since I made the inside 45° to avoid overhangs.
This way will barely necessitate supports, at the bottom curve, and even then they could probably be avoided at the cost of some minor cosmetic defects.
I used a 4 line brim to make this stick well directly on my glass bed in this orientation.

This can probably be scaled successfully (and very easily) to accommodate for different hand and rope sizes.
