08/2025: Updated 3D models for the screw and the center piece. The screw is now hollow!
With this parts you can convert your empty Prusament spool to a Masterspool.
I tested several other Prusament to Masterspool adaptors, but none of them were perfect. Therefore I created a remix with modified parts:
The labelholder is adopted unchanged from the “Your last spool” adaptor.

The two screws are adopted unchanged from the “Prusament black Spool Core Reinforcement […]”:

The center part is a complete new model from me, similar to the “Prusament spool to master spool adapter”:

Among others I resized it in favour of a less tight fit to the Prusament sidewalls and the filament roll.
You can print it on your Prusa Mini in one single print.
I printed the label holder in PETG, but the center part and screws in PLA.
Cut the zip ties from your new filament refill after you have assembled the Masterspool. You can easily pull them out with a plier afterwards, if you loosen the screw a bit.
