Spool Holder (minimal material-used design)

Spool Holder for a variety of spool. The point of contact to the spool between the front and back roller is 9cm. You can use 1.75mm filament as the pivoting axle for the rollers. Ensure all the 2 halves of the rollers are permanently glued, and free running before securing the axle tips with a drop of cyanoacrylates.
