Filaments.ca MasterSpool Adapter

To use this, mount your Master Spool compatible filament to the adapter and out the adapter onto the female half of the filaments.ca master spool. Please mount the adapter face side first (filament side facing out). Then, secure the end of the filament in the respective hole (ther are two, one or 1.75mm, the other one for 2.85mm), and screw in the other half.
Filements.ca has launched their own master spools, called Econofil. They hold 1kg of filament, and are very good bang for the buck. Howev
