Photos are just for a Demo, you can assemble this anyway you like, also with or without the Middle Frame, the arms can only hold 1806 motors and maybe smaller, but i haven't tried that yet, also there is a cutout for the ESCs in the arm.

I made this 180mm because my print bed is pretty small and I love how strong and durable these mini quads are, this takes about 7-9 hours depending on how much infill you want to print with.

Quantity:
1 Bottom Frame
1 Top Frame
4 Arms
1 Middle Frame (optional)

Suggested Parts:
ESCs: http://www.banggood.com/DYS-BL16A-Mini-16A-BLHeli-ESC-OPTO-2-4s-for-RC-Multicopter-p-975796.html (These will fit perfectly)

Motors: 1806 2300KV motors will fit (X or + Mounting)
Smaller motors might work but try at your own risk

Props: ABS or Carbon 3030 Props http://www.banggood.com/Gemfan-3030-ABS-Propeller-Prop-2CW2CCW-4-PCs-For-RC-Quadcopter-p-1005548.html

Flight Controller: One that's 36mm x 36mm will fit perfectly

PDB: this is the one i have mounted in the photos

Battery: 2-3S I have a Zippy Compact 1500mah but a 1300mah may fit better
Something with a 60C should work good with the 16A ESCs

UPDATE: 2/11/2016
ADDED 3 Mounts for the top of frame - link: https://www.myminifactory.com/object/mounts-for-arkadia-180mm-quadcopter-18533

1. A Gopro mount, I recommend using short M3 bolts and some matching locknuts to secure mount safely (nylon screws used only for demonstration)

2. A 22.5 degree tilt designed around this camera ( http://www.banggood.com/600TVL-8_0MP-14-2_8mm-CMOS-FPV-170-Degree-Wide-Anlge-Lens-Camera-PALNTSC-p-984345.html ). I used some 3M double sided tape to secure it to my frame but the lens hole is pretty precise after you clean it out after printing.

3. A no tilt mount designed around the same camera above. I used 3M tape to secure the camera to my frame with this mount also.

IF YOU GUYS NEED A 45 DEGREE MOUNT LET ME KNOW IN THE COMMENTS AND I'LL MODIFY THE DESIGN AND ADD IT.

Any questions please ask ! Enjoy this frame !
