Designed and printed this adapter to fit the air mattress from Lost Horizon for the Tesla Model Y. The inlet/outlet on the mattress is bigger than conventional adapters and I couldn't find one online. 

Should fit the mattress snug so it can support the weight of the pump.

Printed the model upside down (small to big). The part that attaches to the pump should fit other flextailgear pumps as long as the diameter is 20mm :)

This is my first time making something using Fusion360 :)
