My Waterpic Model WF-07W gave me a problem. Over the years the magnet that holds the wand of the water pic at rest has weakened so the want doesn't stay but falls over messily.

I printed in PLA, 0.3mm layer height, with organic supports, a bracket that press-fits into the oval cutout in the base of the waterpic and supports the wand so it stays in place until I'm ready to use it.
