This is a threaded ring to help stabilize cardboard spools for rolling filament holders. The two pieces thread together around the cardboard spool.
No Supports Needed
Cardboard_Spool_Adapter1_No_Keys has the “keyed” extruded pieces removed that fit into the cardboard cutouts on the California Filament Spools. This Version may fit other cardboard spools. Would recommend checking the dimensions on the spool to see if it will fit your other spools.
Please leave feedback on the design and we will work to make this the best we can.
