FM12/S10 Standard Module - One way valve (Patreon)

Hey all,

small upload here. The standard module contains a hole through the middle. I have designed  a small oneway valve which can be fitted inside. 

I will attach pictures shortly, however to get this to work, you will need to get something which works well as the valve. I used 1mm silicon sheeting which I have cut to size then hole punched one in the centre. I will provide visual instructions soon.

I know this is not much to go on, but I hope some of you can find a use.
