Prusa LCD Knob
thingiverse
There are countless designs for knobs out there tailored specifically for the Prusa, but none of them met my requirements due to their size and design flaws. The original knob from Prusa features a lever that doesn't make sense to me at all. So I decided to create one that perfectly fits my needs. My custom knob stands 11.5 mm tall with a diameter of 20 mm. I printed this custom part in PETG with an infill of 100% and a layer height of 0.2 mm, but it can also be successfully printed in PLA. I opted for PETG simply because I wanted the new knob to match seamlessly with the rest of my Prusa parts.
