Gravitrax Compatible Trap Door Print in place!

Here is a Gravitrax compatible switch that close once the first ball falls in the hole.
the base plate needed is the six exit base plate by alex80it (https://www.thingiverse.com/thing:3552100) (or equivalent).

Print in place! no support or brim needed.
10% infill, works fine. ( if you decide to fill more, it will slow the swing, and add more counterweigth)
Print in PLA works perfect,

feel free to comment, and to like it, I'd love to get feed back and see your makes!
