I needed a bit more room on my print bed and the only thing preventing that was the fender washers on the Y bearings. The Y carriage was bumping into them so I decided to replace them with flat sided ones. This is my first "real" part here on thingiverse. So I hope someone actually uses it and likes it. Thanks for any constructive feedback. Ver 1 was too big! (60mm diameter) Ver 2 slot seems a bit small. Ver 3 Should just end on the flat side right next to the 608 bearing, Added a couple of clips that might help. Ver 4 Removed one of the clips, lowered the height to just under 2mm
