You can print them or in ABS or in PETG.

If you use PETG, be very careful with your PEI, as this material sticks a lot

Follow the rules in the material section found here :


Nozzle temperature: 240 °C

Bed temperature: 80 – 100 °C (Bigger object bigger temp.)

Surface preparation: Make sure the surface is clean. Do not use isopropyl alcohol to clean the bed, or the adhesion may be too strong, if you do not have anything else on hand use the bundled glue as a separator after cleaning it. Windex or similar windows cleaner is great option for PET and you don’t need to use the glue after the cleaning. Pour a little amount on unscented paper towel and wipe the print surface.

BTW, the STL files can be found here :
