Weep Port for Camper Floor

thingiverse

I recently encountered some rot problems in my camper floor so I decided to replace it while adding a system to ensure easy drainage of standing water from hard-to-reach areas, such as under cabinetry. This weep port is designed to fit through a 3/8-inch hole with a 1-inch top flange that can be counter-sunk for a flush fit with the surrounding floor. A flange nut threads into the bottom of the bolt to sandwich the floor, followed by a threaded wingnut cap to prevent critters from entering. The flange nut features a hex bolt head, but it's not intended to be tightened too tightly - finger-tight or slightly snug should suffice.
