Scroll wheel for extruder idler for Prusa i3 MK2(S)
thingiverse
I frequently adjust the tension on the idler as I built the scroll wheels, allowing me to swap out parts quickly without needing an allen key. To replace the original screws, you'll need to use M3x40 hex (ISO4017) fasteners instead of the standard M3x40 ISO4762 screws.
