Bagpipe Bellows Adapter, 17mm

I've made this adapter for my new synthetic bag. It can be used with 16mm inserts(or more or less, depends on the hemp.

I've made the small one first but then cut the hole to big. So I needed a much bigger one which is not estetic at all.

On the pictures you can see one in action (black 0.1), one leaking (black 0.2) and one working but to small (white 0.2).
