Filament Roll Spool Hub 55mm x 65mm

I made this for standard 3d printing filament rolls with 55mm opening
the dimensions are aprox. 55mm round(main) x 65mm tall and the center hole is 10mm.

This helps the filament roll spin freely during printing and puts less stress on your extruder when extruding filament.

I have test printed this and it works great! ENJOY!
