Filament spool axis

Description

This is a conic axis (for 48 to 54mm I guess) to be inserted into the filament spool to keep it perfectly balanced, so the effort to move it is reduced. Two pieces need to be printed. Central hole is 8mm. I replaced it with a new design including 8mm bearings, so now it turns softer. This is a tapered shaft (between 48 and 54mm I think I remember) to insert it into the filament spool so it stays perfectly balanced. This way the effort to turn it is less. It takes two pieces and the center hole is 8mm. I replaced it with a new design with 8mm bearings, so it turns better now.
