55 MM Filament Spool Roller

I made this because I recently purchased a roll of igus.de's iglidur i170-PEtribifilament for a project and I needed something for the filament to roll on as I fed it to the printer.

It's not fancy but it works. The STL file contains all you need except #16 x 1.25" Wire Nails to hold the rollers in place.

For best results print at .2 layer. I found the nails to be a little loose but a drop of glue on the tips took care of that.
