Printed well but did not have enough grip to the board to hold on - with a full spool it fell off. But I really like the design so I ended up designing a variation that is bolted onto the board.

Easy to print but doesn't hold onto the Multiboard well enough to withstand a full roll. ANd after it fell the first time it got weaker and weaker. Good idea but needs a bolt.

Easy to print and does work. I think it needs a few tweaks to make it better. My rolls wobble back and forth quite a lot and they don’t quite ride on the bearings as the roll moves back and forth. Overall it’s functional.
