Nylock Nut Knob
thingiverse
For a couple of years, I have been using the Prusa Mendel Filament Spool Holder, which I designed. However, I used a box wrench whenever I needed to change filament reels. Realizing this, I decided to create a knob that press-fits onto a 5/16" nylock nut, making it possible to change filament using bare hands. This modification is an improvement and makes me more willing to change filament for different colors. To install, print the attached STL file, sand as necessary, and use a bench vise or pliers to press-fit the knob onto the nut. Then, screw the knob onto the Filament Spool Holder's shaft in place of the original bare nut. Finally, put away your wrench and enjoy the convenience.
