Filament Spool Adapters for Large Rolls

Measured to fit my Deeplee rolls, and can fit other brand filaments with a similar sized spool hole.

There are now 2 sizes: A is the biggest, and B is 1% smaller.

This adapter is fully insertable, but I found it to work best partially inserting the adapter. It’s easier to remove once your filament is out and you can move the adapter to a new roll. Also, it even acts as a spacer.

Dimensions:

Layer height 0.20, nozzle 0.20, infill 15% (but you can go down to 10% without risking durability)
