Quick and dirty Ball bearing upgrade

thingiverse

In an even dirtier version of a ball bearing upgrade, replace the fender washer with an M16 washer and use superglue gel instead of epoxy for attaching the washers. This method took less than five minutes to complete and has been working on a reprap for years without any issues. However, be cautious as using an M8 washer inside the M16 opening might cause it to catch due to manufacturing tolerances or centering of the washers. To avoid this, try different washers, file/sand the M8 smaller, or center it before tightening the nut. Using the nut directly against the bearing seems to work well. For added precaution, use a round file to make the M16 slightly larger inside for better fit.
