Customizable Prusa to Master Spool adapter

I have found some "Master Spool" refills and models, but many of them seemed to use different widths. This time the adapter had to be 50mm wide (for Form Futura 750g refill). I redesigned the original model so that I can change the width arbitrarily in the future. As long as the inner diameter fits (approx. 100 mm), you only need to change the required width (model height) in slicer. Two examples (50mm/60mm) can be found below. Changes: this will fit tighter than the original model tight enough so that the parts do not fall apart but still are removable removed the text removed the inner ring simplified for smaller file size
