Try this before you print the bearing- https://www.thingiverse.com/thing:3569489
608 bearing dimensions but in 3D print style (wont lock up) ;D Takes 20 minutes on my delta printer :D
IF YOU HAVE PROBLEMS WITH STICKING BEARINGS TRY THE "ULTRA EASY 608" or the "EASY PRINT 608." On a side note, you can lower your extrusion rate by 1-2% depending on your results. Or if your bearings fall out when you take it off the bed, increase your extrusion rate ;D
Also could try this 2 minute print first to verify your printer- https://www.thingiverse.com/thing:3555815
Make sure you follow the directions in the second video. Its rough in the beginning but if you work with it a little it spins even without any lube ;))))
UPDATE 1: I added a rod .stl to help with the smoothing process ;)
UPDATE 2: Added Beveled.stl style for easier entry into parts.
UPDATE 3: Added a beveled 8.1mm and 8.2mm bore version for easy fit and printer tolerance levels. (JUST FYI, the beveled ones are harder to loosen)
UPDATE 4: Added Beveled 608’s with 8mm, 8.1mm and 8.2mm bore with 1.2mm spacer variants.
UPDATE 5: Added a 2 in 1 608 for science. This is expirimental. 22mm outer, 8mm inner, 14mm width.
UPDATE 6: Added Drill Bit Tool (keep in mind heat will cause pla to fuse so don't overdo it :D) and an easier print 608 (functional, checked twice)
UPDATE 7: ULTRA EASY 608

-Sticking bearings? Decrease extrusion by 1-2%
-Bearings Fall apart? Increase Extrusion by 1-2%
The correct profile makes a huge difference!!!

I used the 8.2mm Bore Variant for this project because the peg is exactly 8mm so it wouldnt fit. This is great! Definitely staying on my desk xD

I currently do not have a multi material capability printer so I will hold off on making this for now. It will be the first thing I make when i get to that point though :D
