Large filament spool holder

thingiverse

I needed a spool holder that would accommodate our larger reels at the local hackspace and tried out several existing designs available here. I found them all too complicated, so I created a simpler model that incorporates bearing axles directly into the shell. Only four parts are required to manufacture each roller, along with two (608) skateboard bearings. This means you'll need four bearings for a pair of rollers. Simply insert the bearings into the wheels and then secure them between the two sides. It relies on friction fit, so some force might be necessary. I used Innofil Pro 1 PLA for the print as it's significantly stronger than regular PLA, yet prints exceptionally well.
