Summary

This is a spare filament spool which I have designed to hold a shorter length of filament (e.g. leftover ends joined together into a longer strand). It is modelled from a regular Creality PLA spool, but only 130mm (5 inches) in overall diameter. The spool sides are formed as hexagonal meshes to save weight and material. The spool fits the Ender 3 and similar machines.

It is printed in three pieces, two sides and a central spindle. These are press fit together and permanently fixed in place with some crazy glue.
