Dry Bilge System

A typical boat bilge pump leaves 1/8 inch of water. This dry bilge system soaks up the remaining water that you can pump out.

There’s similar designs out there using a power or light switch blank, but I found they were too light and would not stay flat. I designed this with baffles you can fill with BB gun balls as it’s printing. The BBs weigh this down to stay flat. Attach a sponge to the bottom and a hose from your pump.
