The Marswork refillable filament spool, assembled

Marswork makes filament storage and spool refilling simpler, faster and more secure. It is built as an easier alternative to traditional refillable spool systems: two top locks hold the filament, so there is no aligning and rotating of two spool halves.

Two velcro straps hold older or partly used filament in place, which keeps loose ends under control and storage tidier. Whether you are loading a fresh refill or managing filament you have already opened, it gives you a spool that behaves predictably.

Simple to lock. Secure to store. Better for everyday printing.
