Caster Wheel Socket for 1/2" Square Tubing

thingiverse

This is a replacement socket for a caster wheel that fits snugly in 1/2 inch square tubing. The part was made to replace worn out sockets on a Critter Nation small animal cage, but should fit any 1/2" square hole that is at least 1.5" deep. The part is purposefully slightly wider than 1/2", this is because the spikes are meant to be squished as the part is inserted, so that friction makes it stay (just like the original, hence the eventual tear once pulled out, and the potential need for a replacement). Because of the snug fit, it's important to use a 0.1mm layer height, or some of the details (specifically, the pointy end of the spikes which are meant to rub against the inside of the tube) will disappear in the print, resulting in too loose a fit (if this is still the case for your printer at 0.1mm, try 1% incremental scaling factors). As always, YMMV, good luck :)
