I remixed the original Prusa Control Knob to have a hex head. I included two options. One with a solid head (see Orange photo). The second has an separate inlay that can be printed in a different color and glued in place (see Black photo). I also added a color change at the top of the knob for a little more color in the finished Black one.
I printed mine with a 0.1mm layer to get finer detail in the small parts. You should use a brim to keep the parts stable.
Please post likes and make if you like the design!
