I designed this spool to fit a 75mm D3D Sigma filament refill using minimal filament to make. The slots in the outer spool make it easy to load the filament before cutting its zip ties.

The SCAD files are included to provide a starting point for anyone wanting to make a spool for a refill with a different sized opening.

The walls of the spool may be a bit more flexible than some people are comfortable with.

This work makes use of the following libraries:

  • Round-Anything library by IrevDev
  • ISO-standard Metric Threads library by Dan Kirshner

Pictured version printed on Prusa MK3S+ with generic PETG, 0.6mm nozzle, 0.4mm layer height.
