Description

PDF

I designed covers to attach to stepper motors on the Prusa i3 MK3/S/+ and MINI/+. The name of these printers are written on the top, so you can choose the suitable cover for your printer.

You can print the covers by manually changing the filament, and the Prusa MMU2S is not required.

If you have a MMU2S, please print the following model. It can print without supports and the lettered side is flat.
