3 pen ender 3
thingiverse
A mix of a sharpie holder and an ender 3 filament guide I found on google. Used for coloring filament for some fun effects. Update. stuck with the mount design because I'm not planning on using it all the time and wanted an easy way to take it on and off. printed easily with tree supports. May need to drill out the center of the holder to smooth. Seems to be a little rough inside the filament hole of the holder.
