Bike Pump to Coleman Air Mattress Adapter (schrader valve)

thingiverse

Simple insertable adapter for easily inflating a Coleman air mattress with a bike pump or electric pump featuring a schrader valve, commonly found on generic bicycle and car tires, etc. Works seamlessly for other inflatables with the same type of valve, including other brands of air mattresses, kayaks, and large pool toys. The Coleman valve is often referred to as a "Boston valve," but confirmation would be helpful from anyone who knows. Note: When printing this adapter, there's a tiny bit of overhang at the insertion stop, so adjust printer settings accordingly by printing interior components before exterior perimeters, shells, or walls.
