Do you want to keep a micro sd card next to your 3d printer but you always loose it ? Print this lcd knob. That way you can keep the micro-sd card ON your 3d printer ;-)
It's for a creality, but if the diameter of the potentiometer on a prusa (or any other 3d printer) is 6mm, it can fit.
It's about 5g of filament and takes approximately 45mn to print.
