Pulley for Geeetech Prusa i3

thingiverse

This is a pulley for Geeetech Prusa i3 that allows the belt to run without touching the lateral walls. I split each one in two for the simple reason that I wanted the inner limiter walls to be at 90 deg. If printed in one piece, the upper ring could have been at maximum 45 deg., allowing the belt to climb the margin ring when going sideways. The ring parts maintain the center position over the two bearings due to the inner tiny ring fitting in the narrow space between them.
