Master Spool

myminifactory

This master spool is engineered for use with Filaments.ca's econofil refill spools. The central shaft boasts a diameter of 76mm, ensuring seamless alignment with the hardpaper core of these refill spools. To assemble this design, you will need at least two M6 screws and nuts. However, it's possible that the nuts may be too tight for their slots. Four concentric lines on the spool indicate approximately one-fourth its total volume.
