A Prusa styled wing knob with LED passthrough. Made using the clear insides from an existing knob.
There is a version with shorter wings, which I made, due to the fact that the longer wings covered up some of my TFT35 V3 screen. I would suggest the shorter wing versions for this specific screen.

Theoretically compatible with any standard rotary encoder shaft.
The led passthrough is taken from a cheap rotary encoder knob, mine specifically came packed in with my BigTreeTech TFT35 V3. However, this style can be found online for cheap.
I included the Fusion 360 files if you need to adjust it to your specific donner knob. Use flush cutters to remove this section from your knob and simply slide it into the print. It is a tight squeeze and shouldn't come apart easily.
Known to be compatible with Ender 3, Ender 3 V2, BTT TFT35, BTT TFT35 V3 and Original Prusa.
