Irwin clamp filament holder

thingiverse

I've got a stash of spare Irwin clamps just waiting to be put to good use, so this seemed like the perfect opportunity to create a simple filament holder for my printers below. Hopefully, you'll find it just as useful as I do! Just print it out (no supports should be needed), slide it onto your inverted clamp, and you'll have a double filament roll holder in no time.
