The are now four models in the "T" copter series: three quads and a coaxial six - all FREE for download from thingverse.com
I've also just done a short video series following the build of the 315 size T4 quadcopter which I hope might be useful to folks looking for a way to get started with a DIY copter and APM based flight controller.

Build video 1: Body assembly
Build video 2: Install motors
Build video 3: ESCs and power
Build video 4: Flight control

Thanks Leonard. From you I take that as high praise :-)
My wish is not to prove that 3D printing is the best way to build copters ...just to show that it can work, and actually work pretty well!
If you want to build a 3d printed copter I highly recommend that you start here. Even if you want to design your own. Look at these designs and understand why they have been done like this.
Nice job!
As I have looked at these designs it seems they would benefit from a hybrid approach using a combination of materials and allowing the 3d printed parts to be only of the center body and then using standard stock for the arms, with maybe 3d printed connections

Looks great. Very solid flight on https://www.youtube.com/watch?v=5KLcN-zDI7c.
How heavy are the frames?
