A simple set of filament reel rollers small enough to fit in your pocket, but big enough to do the job.
OpenSCAD was used to model the reel roller, and the design drivers are:
Use the least amount of non printable hardware as possible.
Easy to set up and put away, as working space is limited.
Small enough to drop in a box for storage and transportation.
To fit any size spool.
All the parts available on Ebay.
To make a pair of reel rollers you need to print four sides, two per unit.
