Three-Pivot Dehumidifier Float Lever
This replaces the cracked float arm in a dehumidifier bucket. A broken arm stops the unit from running even when it still works. The lever is 162 mm long with a sealed hollow float (40 x 24 x 14 mm, about 13 g of lift). It has three 3.4 mm pivot holes 10 mm apart that take a 3 mm steel pin or an M3 screw, so you can choose the lever ratio, and a 12 mm tall switch flag you can trim to the length you need.
