I took Engidahvs' model, along with the PC4 M10 arm from BC, and extended it out 25mm to be more centered with the spool. I then joined them so it can be printed as one, solid model and added an elongated support so it's sturdy.
This is for use with the Filler. Filler filament holder files included and are the original's from HugoG.
The author remixed this model.
