Smooth UL QMX knobs

UPDATED 4/29/2026: Now on Version 2, Improved compatibility with QMX case. Increased diameter by 1mm. 

These are the same as my minimalistic ultralight knobs but with fancy grooves! When printed in ASA-GF these low profile knobs weigh just over 1g! The knobs that ship with the QMX weigh 7.7g. I wanted something ultralight, that sat as low as possible.

Prefer a knob with grooves? Print both styles and choose your favorite.
