UPDATE 23.06.21: I still had some issues with spools slipping of the adaptor, so I increased the angular size of the clips a bit and slightly increased the diameter too. I guess now it holds nicely. If you have problems mounting this version in a spool (probably extrusion factor related) try scaling x and y (not z) down 1%…

UPDATE 26.04.21: Slightly increased outer diameter, because it turned out to be a bit loose. Now it's a pretty tight fit and also able to hold a full 1kg spool…

Adaptor to mount Prusament spools on a shaft of your choosing. Included and on the pictures is the 10 mm version. I am using this right now to remix a dry box design for 2 spools (see this).

I have included the .f3d file with 3 parameters to change diameter of the spool, the shaft and the distance for the clips to fit with Fusion360 (see picture). Don't forget to include tolerances.

For non-fusion360 user there is the .step file to adjust the model…
