Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5143853.
The original RatRig spool holder V2.0 is a little short for bigger spools, so I made a longer version.
I remixed the original model I got from the RatRig Github (link below) so I can't make a direct reference to the creator with the remix function. The model is just elongated and keeps all the features like grooves for PTFE tubes. The mounting positions hasn't been changed so it doesn't require any changes except for removing the original part. You didn't have to remove the endcap from the extrusion.

Depending on the print orientation and the desired quality you can get away without supports and raft. If you print it like me with the triangular part pointing down a raft is highly recommended because the contact area is very small.
Even though it is published as open source project I wnat to make clear that I didn't deserve any credits for the model and that all rights are preserved by RatRig.
