Dive Gate triangle with pipes

This is a simple project to make a dive gate with 6 tubes and 3 adapters.

V2 added with slightly enlarged tube holes, recommended to print this one, as the original one is very snug fit.

The foam is optional and its only to help you to identify the exit side.

The join adapters should be printed in TPU or similar elastic/rubber stuff.
The adapters are really heavy duty and will probably last more than the tubes itself.
