About this 3D model

This is a redesigned holder for a filament spool. This assembly is for a spool with a 75MM inner diamer hole. You will need 2 ea Cap Nut, 2 ea Spool Inserts, 1 ea Spool Shaft. I used this video from Product Design Online to better design the threads in Fusion 360. STEP File included in download. The Spool is there simply for reference, although i suppose you could export it and print it out if you need one.
