Xiaomi YI 4K+ Fast Extract Rugged Case (non-waterproof)

I was looking for my Xiaomi YI 4K+ with following properties

• rugged
• with GoPro mount
• easy to extract for fast battery exchange
• all buttons, micros, speakers and the display open
• possibility to attach external peripherals (ext. micro, flashlight etc.)
• with a locking door which prevents the camera from falling off

Unfortunately, I wasn't able to find something and decided to design my own.

Required Hardware:

• 3 pcs. M3 x 16 mm countersunk head screws
• 2 pcs. M3 x 8 mm (10 mm possible when using nylock nuts)
• 2 pcs. M3 hexagon nuts (or nylock nuts) 

Recommended printing orientation as per attached screenshot. I printed my in PETG, I recommend to to print at least the latch arm in PETG. I didn't test other materials so far.
Enjoy :-)
