Having just finished building my Recreator 3D PET 1 bottle filament creator, I wanted a way to use even more of the waste bottle and thought, wouldn't it be cool to use the bottle caps as LCD knobs….. Well now you can :).

You can simple screw the bottle cap onto the adapter and then push onto the LCD, want to change the cap for another just remove the adapter and unscrew the cap and replace it with a different one.

Print in whatever filament you wish, I've used PLA @ 0.2mm LH and 20% Infill here.

Added an adapter with less standoff from the display.
