Prusa Frame Prusament Spool Holder Auto Rewind

Prusa Mk3 frame Specific. Primary reason for this was filament sometimes on new spools coming off the spool. Like on an auto Z calibration or when I Move Z up to much with a new spool.

The Spring is a one way spring. The holder is designed to mount the spool only one way.

The rewind spool was modified form the great design by Vincent Groenhuis https://www.prusaprinters.org/prints/168-universal-auto-rewind-spool-holder-mm

I am not interested in creating different sizes our variations for different filament spools. I'm a Die Hard fan of Prusament filament.

These stl files are for single color. If I have extra time I may update with the Multi color stl files since I would need to re-export them. If you have fusion, you can export them out.

The fusion file was cobbled together from different projects. It will do for anyone wanting to mod this.
