(Tuya) Smart Knob Dimmer sleeve

This Smart Knob Dimmer sleeve (bearing?) will make the knob operation less wobbly and gives the cheap device a confident touch. “It punches above it's weight.”

But kidding aside, the sleeve minimizes much of the wobbliness caused by the slightly oversized knob. 

Make sure your printer is set up properly, as this design fits neatly only if your printer's dimensional accuracy is spot-on (-ish).

Important: The “lip” at the bottom is actually a 2x 0.5mm line brim with 0.0 mm gap.

(Yes, a piece of paper would have worked too, but what's the fun in using that?)
