About this 3D model
An adapter for $5 filament spools. The spools used by ProtoParadigm are creative but they will jam easy on a spool holder. This adapter can be a little tight to fit into the spool but thats intentional because if the spool comes loose your print will jam. This object was made in Tinkercad. https://www.tinkercad.com/things/k3Udh4fwT8s
