Quadcopter with removable arms

Thingiverse website is pretty crap. I typed in a whole lot of description, photos, etc and it lost them once I clicked Publish :-(
Not typing all that in again. #webdevfail
EDIT: I uploaded the wrong STL file for the arms. Have replaced that now.
EDIT: I have made a custom case/battery tray for the FireFly mini camera, mounted with anti-vibration balls. The video is now much smoother and jello free! The related STL files are now added.

EDIT: I have installed a Runcam Split Mini now, and the video quality is heaps better. Here's a sample: https://youtu.be/lAaHbOSYLb4
I designed a new mount for this, and have uploaded the STL file (holder-runcam.stl)
