Improved idler for Prusa i3 MK2(s) extruder
thingiverse
I rarely use the idler, but it's not exactly finger-friendly. To create a more comfortable design, I modified the original file from the Prusa Git repository using Tinkercad. The new version fits both MK2 and MK2s models perfectly. Update (03/11/2017): I added a screw head cap to make idler handling even easier. First, place the screws into the holes of the printed cap. The holes are designed to fit snugly with the screws. Next, add the springs and securely fasten the idler to the extruder body.
