eSun produces some transparent reusable spools which can be separated by removing two bolts. This design makes them compatible to the Masterspool conventions by RichRap. There is a generic version available that meets the original Masterspool dimensions (46.7 mm width 102 mm outer core diameter), as well as a version which is optimized for DasFilament PETG refill bundles. They commonly seem to have a larger core diameter. The adapter uses as little material as possible and also features a notch to attach the filament end.
Additional parts:
- 2x M6x35 mm screws
Printing:
- PLA / PETG or ABS if you use a dry box etc.
- arbitrary layer height
- 15%+ infill
- 3+ perimeters
- no supports
Assembly:
- Place the M5 nuts on a flat surface and one half of the eSun spool accordingly:
- Insert the printed adapter piece and the refill bundle. Put the filament end into the notch and take care of the alignment of the cable ties.
- Attach the second half of the eSun spool. There is also a small notch on the outer ring. Align the filament end accordingly. Turn the pieces until the holes for the bolts are aligned properly:
- Insert the two M6x35 mm bolts and slightly tighten them almost hand-tight:
- Cut and remove the cable ties. Take care not to tangle the filament start by putting it through the provided holes on one half of the eSun spool:
- Finally, tighten the bolts completely :
