Prusa Mk2 / MK2.5 Adjustable Y idler
thingiverse
This is a remix of Jooxoe3i's Y-idler (https://www.thingiverse.com/thing:461824) I've adjusted the idler tensioner to fit on the original Prusa i3 MK2/MK2S/MK2.5 Print two sides, the spacer, and the pusher. You will need: 1x M3 nut 2x M3 lock nuts 1x 18 or 20mm M3 Screw for the pusher 1x 30mm screw for the pulley The standard Prusa pulley should fit on this idler. I used a toothed GT2 pulley to reduce wear on the belt. Pulley (20 Teeth) - 12.2mm Diameter, 18mm Flange- 3mm inner diameter (https://spool3d.ca/pulley-20-teeth-12-2mm-diameter-18mm-flange/)
