PolyBox Extension (Centering)
thingiverse
A lot of people who enjoy the PolyBox and large 300mm / 12in diameter spools, like the 2.3 kg spools from FormFutura, have found that the box is wide enough but a bit too short. This problem has been solved before (check out the links below), but I wanted to add guides to center the spool and prevent it from rubbing against the rounds. Speaking of the rounds, I made sure they were C2. My printer's 12" square bed can't fit the size, so I'm using the split version that can be joined with a pair of 6mm or 1/4" fasteners.
