A superior filament holder boasting a main bearing coupled with additional ball bearings to minimize friction. The arm guide is designed with a hollow interior, allowing the insertion of a piece of foam to serve as an effective filament cleaner. I included a washer due to a tolerance discrepancy of .8 mm. The threads on the cap are also suspect and inadvertently reversed; scaling up by 5% would render it suitable for a press fit cap. Bearing specifications: * Primary bearing: 35mm from Ace Hardware * Secondary ball bearings: 8mm, sourced from Ace Hardware This design effortlessly glides with ease. Print settings: Printer brand: Printrbot Printer model: Simple Black Layer resolution: .2mm Infill percentage: 50%
