Included in the files is an STL for a custom M3 screw. The screw is slightly longer than the ones on the face of the Sprite Extruder, this will allow the Alien plate cover to be mounted, as without the original screws are too short. Be mindful when threading in the custom M3 screw, tighten slowly so that the screw doesn't break due to too much resistance from any misalignments in the printed threads.
Smoothing: Used a wood burning kit to melt down the layers, giving the forehead a much smoother look.
The author remixed this model.
