Jump Rope

thingiverse

I crafted this jump rope handle with a rugged grip to ensure a secure hold even when your palms are dripping with sweat. To assemble it, you'll need 13x5x4 bearings, but make sure your printer is finely tuned – any calibration issues will cause the bearings to struggle greatly as they try to fit snugly into place. A rubber mallet might also come in handy to coax them into position.
