About this 3D model
Alternative Y Motor mount and Belt tention. for use with professional Belt pulley (Rolle.scad) I haven't printed the pulley, as i use professional ones made of aluminum with ball bearings. If you find a closef belt that fits into your Mendel Max you should use the 'Umlenkrolle Aussen Adjustable.scad' for belt tention adjustment. if you use a open belt you can print a second 'Umlenkrolle Aussen.scad'
