Spool Hub for Virtual Foundry Copper Filament

thingiverse

This design is tailored for use with the Virtual Foundry Copper Filamet 0.75kg spool and is specifically engineered to work seamlessly with a 1" shaft. The filament can be notoriously fragile, prone to breaking off the spool at the slightest provocation. In my experience, even moderate tension between the wall-mounted spool holder above my printer and the extruder was enough to snap the filament on occasion. By allowing the spool to rotate more freely around the 1" bar on my spool holder with reduced tension, this design mitigates the risk of breakage. It's possible that this solution may also prove effective for use with other spools.
