Master Refillable Spool - Filamentive Economy Spool Replacement for AMS/MMU/ERCF/Reprak

This is a simple no hardware required, easy to print spool, Simply cut away the cardboard spool and fit some cable wraps/ties around the filament, slide it off the cardboard, onto the plastic then screw the 2 halves together and snip the ties, you now have a fully usable filament roll for use with edge rolling spool holders and AMS.

Feel free to ‘cut’ the male part to shorten the threads, 2 turns is more than enough, so save filament and time by cutting it down in your slicer.
