thingiverse
A 606 skate bearing fits with an inner diameter (ID) of 22mm and outer diameter (OD) approximately 44mm, suitable for replacing standard laser-cut idlers. Thicker at 5mm compared to the laser-cut version, this modification reportedly performs better than its predecessor. Despite not having tested it in an extruder yet, it's expected to function without issue.
