Description

Knob enhancer wheel upgrade - It adds 3:1 ratio while turning, I've made it specifically because I was annoyed by temperature and fan menus that require me to do 21 half-rotations of normal knob, WHICH IS BAD UX AND YOU SHOULD FEEL BAD ABOUT IT, PRUSA. JUST FIX IT IN FIRMWARE PRUSA, ITS NOT HARD PRUSA, JUST START MULTIPLYING ENCODER TICKS BY 5 AFTER PASSING 20 TICKS IN 2 SECONDS PRUSA.

So, at the end, I've made something that'd let me reach 295 from 0 faster and in less annoying way than with original knob (yes, I know I can pretend Im an airplane pilot and just spin it with my finger - THATS BAD UX )

You might want to use two pieces of 2side tape, to make it secure.

Tolerances are pretty high, so it might feel loose, you can adjust the model as you want (just change diameter of inner border in large wheel to make it sit tighter).

Otherwise, it should be pretty straightforward to assemble and install.

 

Print knob upside down.

Rest - use common sense when placing.

You'll need 2x DIN914 screws, at least 30mm in length.

Check license if you are planning to make it for another printer, e-mail me for written licence permission.2
