spool holder (adjustable, stable, smooooth)

Hi

I wanted to design and develop an easy to build and stable filament spool holder that is also adjustable for different spool widths. I had a few standard aluminum v-profile wheels laying aroud and decided to use them for the spool holder. I also wanted to design one where you do not need many different parts...

to print:

4x spool holder alpha 2 bracket
1x spool holder alpha 2 mount

you will need:

8x M5x25mm screws
2x normal wood screws (diameter not over 4mm)
4x standard re
