Button Box Knobs

3/14/2021: Update, added 22mm diameter version. Fits 6mm shafted rotary encoder.

Remix of RCHeliGuy's fabulous button box knobs. Check out his Sim Racing things. He's a quite talented designer, in my opinion.

His knobs were too large for my AMSTUDIO button box. Also they were not sized for the 6mm rotary encoders I used to make my box. The shaft holes have been sized to 5.9mm which provide a snug fit, yet can be removed easily.

The knobs themselves have be resized to approximately 60% of their original diameter, and shortened so they don't stick up so high. I couldn't get them smaller otherwise the text wouldn't print. I used Microsoft 3D Builder to make these modifications.

I also added 3 more buttons with different labels: There is a blank knob that you can add your own text too; a Front Rollbar, a Rear Rollbar, and RCHeliGuy's original Brake Bias, TCS, and ABS.

Since these are roughly 1/2 the size of the originals, the finer you can print them, the better the lettering will be.

These are "obj" files which work great in Prusa Slicer... I assume other mainstream slicers will not have an issue with obj files. If they do, just pull them in 3d Builder then "save as" stl.
Enjoy!
