Grooved Screw (and Nut) for Prusament Spool to Master Spool Adapter

This is a modified screw for the Prusament to master spool conversion file found here: https://www.prusaprinters.org/prints/1127-prusament-spool-to-master-spool-adapter All credit goes to Zoltanf for posting.

I made the grooves to align with the modified nut made by Hobson318: https://www.printables.com/model/1639-modified-nut-for-prusament-spool-to-master-spool-a 

I added the edited step file and Fusion360 file too
