Prusa i3 Mk2 Mk3 Mk3S Easy LCD Knob
Description
The control knob of Prusa i3 printers looks good but isn't actually very ergonomic, or nice to use when you want to scroll quickly (like setting a temperature), so I took the dimensions of the original and created this version with 4 curves that your thumb or finger naturally sits in to turn it. If you want the recessed top to be as smooth as possible, print it at the lowest layer height your printer can do. Otherwise 0.2mm layer height will be fine. I printed mine in original Prusa orange PETG, variable layer height, 0.05mm at the top, 0.2mm for the rest. You can sell prints of this, but don't overcharge, and link back here. Tips are most welcome https://www.paypal.com/paypalme/Haku3D and will encourage me to make more designs for everyone to benefit.
