AirStream Splitter - MEC 5.0

Hi all,
Here the goal was too split airstream of a airspring-carabin with 4.5mm 0.177 ball pellets
-walther picatinny accessory rail ( laser aim )
Balls or pellets are locked with a center magnet.
Need adjustements , I miss time and a printer!

Maybe it could create a lot of interest for a classroom, it could be adaptated and improve to be used with a blowpipe for example...

Best Regards
JJ
