2020 v-slot filament spool holder

This is my design for a filament spool holder that will fit any 20mm wide V-slot rail. You will need to drill holes for mounting either through the sides or through the top (drill from the inside when drilling through the top) Use with yout choice of T-nuts/V-slot nuts and matching bolts. The threads are a very tight fit and will need finish sanding in order to screw together properly to avoid breaking the roller threads off. I used a few drops of mineral oil on them as well to help.
