FPV tricopter, foldable

Update V0.5
- Integrated Omnimac vibration damper. Download the appropriate top plate for your controller (multiwii and KK boards should fit). If you need a top frame with a different controller layout, like APM or whatever, post in the comment section and I will upload one.
- Vibration dampeners can be bought on hobbyking and the usual places, or you can to print them yourself in soft PLA. I added a printable design.
- Added middle decks for both 12mm and 12.5mm booms.
- Fixed many "manifold" issues causing issues with Slic3r.

Update V0.4
- uploaded new camera house thats >50% lighter than Mochaboy's original, but it will not take a rear cover
- Redesigned plates with smoother corners.

Update V0.3 b
- Increased thickness of middle plates to strengthen it. You can print it with ~15-20% infill and at least 1mm top/bottom thickness to achieve a fair compromise between strength and weight.
- Added some pads for easier printing with ABS
- slightly changed supports
