SUP to bike/car valve adapter

Note: you still need the flexible gasket (print with tpu (see original model) or buy one) and the bike tube valve. 

You need to add supports for the top locking tongues. 

I printed it with PLA with 10 or more walls to make it solid and then…
I found the original SUP pump afterwards, so I DON'T KNOW if it works!  ;)
