Printer Reel Roller

I'm in a rush to change my filament because I'll be leaving the extruder hot, so I need a super quick and easy roller system for the reel. The current one rumbles a bit when pulling the filament but it doesn't freewheel, which is exactly what I wanted. To achieve this, I let the filament feed from underneath, lifting the reel slightly. For bearings, I simply use 1/16 inch welding rods bent at a 90-degree angle and taped on the back. The best part? They're infinitely adjustable with 8mm threaded studs. The Beams print fast with PLA as long as they stay on the bed. For the rollers, fine prints are recommended; you might need to do some extra work to remove any Zits. Make sure the rollers spin freely on the pins after solvent welding them together.
