Wheel and Axle 608 ZZ Bearings
thingiverse
This is a remix of the remix for the Toy Dump Truck by barspin. The bearings mod by Akiland was great but I think my printer is a tad more dialed in. As a result, my parts printed very accurate and the press fit was JUUUUST too loose since the parts appear to be modeled to the exact dimension of a 608 ZZ bearing (22mm OD, 8mm ID, 7mm thick) maybe assuming for shrinkage. Printed in PLA so that didn't shrink. So they slipped together but just as easily slip apart. I modified Akilands parts to snug up the fit, as well as restored the countersink for the screws on the axle. I have included f3d and step files in case anyone needs to tweak the fit further. I also added a test jig file so you can test fit without printing whole parts to chase dimensions. Adjust the dimensions on the jig until you find the right ones, then make that mod to the parts themselves.
