Simple Spool Roller for 55mm Spools

thingiverse

I'm using ColorFabb spools exclusively, so all my rolls are a standard 55mm size. I've experimented with various spool holders in the past and incorporated what works best for me into this design. The rounded interior edges prevent the roll from snagging on the sides, while the bearings deliver incredibly smooth filament feeding. Plus, the small footprint and optimized design allow for a strong print with minimal material waste. For setup, I used a measured length of plastic PVC tubing as a bearing stop, but you can use any suitable alternative like lock nuts or zip ties if preferred. Simply slide everything along the bolt while threading it on. To print, I recommend using the following settings: 0.8mm wall thickness and 20% infill density.
