Filament Roller Support

thingiverse

I wanted a filament roller with bearings supported on both ends that could be mounted in the centre of the printer. I designed a support to use the roller by HugoHuge. You need to print two supports and source two 608 bearings. I scavenged them from an old fidget spinner. With a fairly full 1kg spool of filament, the roller worked too well and dispensed too much filament. With a small 200g spool of filament, the roller worked well. I designed a fixed "roller" that doesn't spin that matches the supports. Without bearings, a 1kg spool is dispensed at a reasonable rate.
