Round climbing feet (rock climbing holds and molds)

thingiverse

CLIMBING IS AN INHERENTLY DANGEROUS ACTIVITY that may result in serious injury or death. Using holds that you find on the internet is really a fundamentally stupid thing to do. Feel free to be stupid and do so, but don't blame me and you must assume liability for your own climbing choices! A set of climbing holds that can be printed directly or for which you can print a mold and pour polyurethane plastic if you want a less slippery hold. The filenames identify the bolt used. They either contain "SHCS" (socket head cap screw) which is the cylindrical head bolt most often used for new climbing holds or "flat head" which is a countersunk bolt style. If you are pouring holds, you should place a washer in the mold when pouring the SHCS versions. The washer significantly strengthens the critical area where people over tighten the hold. When slicing, you can opt to mirror the "big small" holds to create matching pairs of them. I did that in the attached photos. To print directly for climbing, I used PLA at around 2.5mm thick walls and 33% gyroid infill using adaptive layer height from 0.1mm to 0.25mm. To print the molds, I used TPE (NinjaFlex or eSun eLastic) and you can play around with the settings that work best for your printer to minimize the amount of infill and walls but still create a hold that is strong enough to not immediately break.
