Here is a Print-in-one-go spool that mounts an axle with a central roller bearing sized to fit Proto-Pasta filament coils. The spool unfolds to hold a coil of filament measuring 50x30mm in diameter around 160mm. Simply unfold the two parts and push the mount into the hub. Printed in approximately three hours at 0.3mm layer height, 10% fill, 2 shells, and a travel speed of 90mm/s.
