Kept bumping into my other wall mounts, and they'd eventually pull out of the wall. These are much better with saving space, and also split the weight of the bike across 16-20 screws vs 4, so I doubt these will be having any issues any time soon. You'll need 4x 6082RS bearings, 4x M5-30 screws/bolts, rope. If it has holes for screws, print it on it's side, this will maximize strength, I've included a picture of how the pieces should be laid out.

Print Settings 4 wall loops 50% cubic infill. Supports for the pulley pieces. 4x pulley wheel and bearing adapter./
