The box's inside was a bit more complex than I would've liked, but I eventually managed to come up with a bracket with #freecad that just drops into the existing grooves and locks in.

There's a spool that just fits a filament spool and has ball bearings in it. At the ends we have two square pieces, that slot onto the bracket when the spool is lowered into the box.

The outcome is actually faster to load than the original simple holder. Just put the spool center piece in the spool and drop it in place. The big center piece prevents any unwanted movement and the filament feed is now butter smooth! I didn't even need extra parts, I reused the bearings that were at the bottom of the case. I believe they had originally intended to get away with just the cylindrical piece, but that caused rocking motion which again made the spool hit the box sides. They had then added 2 small rollers at the bottom to try to prevent that. Now those are reused in a lot better working design.
