Transmitter tray with foldable neck strap

This is a transmitter tray with plates you can slide out to put batterys or video transmission or anything you want inside. i needed foldable neck holder to put the tray inside mallet to carry.
(Sorry for bad english terms I'm using)
I hope many people will print it and use because I angry shops to sell these parts with a non fair price. I added 3 files of stronger arms because I broke mine.
