Made this filler gun to stage my original Revolt prototypes as a display.
Used all left over filament, hints the multiple colors. Since I did that, it was a great excuse to play with spray painting it with the filler. I was really impressed with the results. 3d print looked way smoother, and took the black top coat evenly.
