Printing on the Original Prusa MK4, provided by member mkg, has the following costs:
For convenience, just pay 10€ per every 1kg of filament you get for printing in realraum. Payments are to be put into the cylindrical container next to the 3D printer in LoTHR labeled something like “3D-Druck Spende”.
mkg: PSA. If you use your own filament it’s 1ct/g, using mkg’s filament 4ct/g total Just ask mkg if unclear.
