Twist quick relase PTFE tube connector

This is version that does not use recessed/protruding magnets to ensure alignment - I have tested that neodymium magnets are strong enough to ensure precise alignment while keeping the end of connector flat.  This solution allows to easy disconnect tubes just by rotating them 90 degrees relative to each other - magnets stop attracting and start repelling. Additional advantage of this solution is that all connectors made this way are compatible (there is no situation when two connectors polarity does not match).

You have to insert magnets like in original design in pairs with reverse polarity (the same polarity opposite each other). 

For one connector you will need 4 cylinder magnets 5x5mm, and one Bowden M10 connector.
