9.2.2019: Added new version 2.0

This is a check valve (one way valve) for filament which can be used for MMU applications.
Use a ball with 4mm in diameter. You can find one in every 608 bearing.

It is meant to be a concept but it actually works very well.

The screw which holds the ball in place could be replaced by a closed canal for the ball and placing the ball in during printing. This makes it airtight too.

Use higher infill density than me so it props the ball well.

Do you have a better name for that thing? If yes: leave a comment, thanks.
English is not my first language and I don't know if "check valve" makes sense.
