One of the dials had somehow broken off during a dive. Made this as replacement. Fits tightly to the metal rod, so it should stay in place. Has a cutout at the base so you can see what it's dialed too.
Print with PETG or similar to ensure it can handle the sea water. A 0.2mm layer height works fine.
Have used mine for 100+ dives now - still working perfectly.
