55 MM Filament Spool Roller

thingiverse

I created this project after buying a roll of igus.de's iglidur i170-PE tribofilament for my current endeavor and realized I needed something for the filament to wrap around as it flowed into my printer. The end result may not be complex but it fulfills its purpose well. You will find everything you need within this STL file, with one minor exception - 16 x 1.25 inch wire nails required to hold the rollers firmly in position. For optimal performance, I recommend printing at a layer thickness of .2. Upon installing the nails, I encountered some slippage but resolving this issue was simple; all it took was applying a tiny amount of glue directly onto their tips to secure them effectively.
