"Blade" Filament Spool "Roller"

Picked up a pair of old "Rollerblade" in-line skates at a garage sale for $2. Removed the axles, wheels, and bearings and designed this filament spool holder from the parts.

I've included the SCAD file just in case you got a different pair of skates...

Note: This thing used axles and bearings from only one skate ($1 total hardware cost). I've got enough left to make another set.
