Prusament spool clamp

The materials used for FFF 3D printing are mostly hygroscopic, and have to be dried.

In order to do so, Prusa recommends temperatures above 45 Celsius degrees for PETG, ASA, PC, PC-CF, etc: https://help.prusa3d.com/article/drying-filament_332086

Regarding Prusament, they mention that due to the cardboard and plastic expanding and shrinking differently, heating spools at temperatures above 45 degrees can make them fall apart.

In practice, it doesn't happen at 55 degrees, so drying PETG at that temperature is fine.

However, it definitely happens when using temperature at 80 degrees and above. As a workaround, Prusa suggests adding screws.

Here's a 3D printed alternative. which should be printed in a material such as PC-CF.

Print flat on the bed, as in the provided files. No supports needed.
