Summary

This is a remix of the awesome 135 micro that Janmittner subitted, here - http://www.thingiverse.com/thing:1091279

I had some parts laying around that I have been wanting to put together in a 3" frame and this design looked promising.

To fit my CC3D flight controller (and any 35mm wide FC), I widened the frame and adjusted the hole placement. I also wanted to use the nylon spacers I had laying around so I widened the holes enough to fit them through.

I wanted to mount an antenna to the top plate so I added a 1/4 through hole.

The best part for me is that this frame actually fits on my 150mm Printrbot bed :)

EDIT 1/18/2016 - I added a FPV pod for the front of the frame to hold a camera at a ~12 degree angle. It integrates into the frame nicely without any additional hardware.

EDIT 1/22/2016 - I added a v2 of the main frame and also the top plate. This will make the top plate a little thicker and adds some more plastic around the bolts that hold the motors in place. These changes should make it much more resilient to a crash. This version is coming in at 196 grams with my current gear.
