Knob for Prusa i3 MK3S
thingiverse
The knob from Onethou wasn't quite right in size for my MK3S, as confirmed by a caliper measurement of the original knob. To fix this issue, I filled in the hole on Onethou's knob, then retrieved the STL file for the stock knob from Prusa. I carefully cut out the hole section from the stock knob and skillfully merged it with the shape of Onethou's knob. And that was it - the modified knob fits perfectly on my MK3S and feels just as comfortable in hand as Onethou's original design. Many thanks to everyone who has contributed to this project so far. I printed the new knob using PETG.
