Mini Bearing Oldham Coupler

thingiverse

I redesigned everything after buying mini bearings. I added adjustable guides to minimize angular movement with z hop as much as possible. Bearings are M3x3x7mm and you'll need 12 M3x10mm (or 12 M3x12mm) screws. It's likely this coupler will work with many other bearing sizes, just enlarge the holes in the Bearing Cross piece accordingly. For all details, please read the description written for the original project: https://www.thingiverse.com/thing:2581521 This coupler eliminates regular z bands of equal height between two bands. If you still have irregular bands then clean dust off the Z rod and avoid using grease; instead use a specific lubricant. You must print 4x Adjustable Guides to use this coupler. Enjoy!
