This Reel Roller is designed to use no other hardware resources at all .

Easily accommodates all sizes of Filament Reel.

The bearing pins are 1.7 filament carefully heat riveted to stop them coming out.

However I did have to clear some filament from the holes through the rollers and the flanges with a small drill . This is probably because I tend to over extrude and the holes get a bit small some times.

Print the rollers one at a time to avoid ZITS when the nozzle passes to the next item.

The roller works well but sounds a little trundley but I don't mind a little noise from the machine and things it proves that all is working well.
