Prusa i3 Mk2 Mk3 Mk3S Easy LCD Knob

thingiverse

The control knob of Prusa i3 printers appears sleek but is actually quite uncomfortable to use, particularly when you need to adjust temperatures quickly, so I studied the original design and created this modified version with four curves that fit naturally under your thumb or finger to turn it.\r\n\r\nTo achieve a perfectly smooth top surface, print it at your printer's lowest layer height setting. Otherwise, 0.2mm layer height will be sufficient.\r\n\r\nI printed mine in original Prusa orange PETG, with variable layer heights, starting with 0.05mm at the top and 0.2mm for the rest.
