Summary
As a designer, I wanted to tackle on a miniquad frame design that showed a REASON to be printed. I didn't want a printed frame to be a choice because "it's cheaper" or "it's free"... but show the qualities of the medium to propel a design idea. If I did my job right, someone may want to proudly choose and fly a printed frame (over carbon fiber) because they like how it looks or how it performs.

I've been building/modding/flying miniquads for over a year now. When I started getting into 3D printing, I wanted to print a frame. There were many to choose from, but I was disappointed. Mostly all of them just took their design cues from the carbon fiber brothers. Flat plates with standoffs.

Hands down the best printed miniquad innovation comes from Hovership, their MHQ2. A great achievement and vision for a printed miniquad frame. Check their frame out

The inspiration for the AG Silpheed frame came from several sources. Firstly, The Zelda Triforce was a huge inspiration for design. The first prototypes used a lot of circles and curves. The first crash led to my arms completely snapping off (stripping the motors from their wires) and the entire frame just got obliterated. On research, the triangle is a strong geometric shape. This led to the design choice of the arms being triangular tubes... and inside it, are more triangles. (the power of the Triforce!) The second inspiration was from roll cages of off-road buggies. The top frame of the AG Silpheed is essentially a big rollcage. It is designed to distribute the forces on an impact - while keeping all the electronics safe.

I have many carbon fiber miniquads in my fleet... but what I like about building and flying a printed frame is that it is continually improved. After every race session or a prox flight in the park, I come home with some new design changes... print them, and they are ready to be installed for the next session. And yes, a broken arm means a cheap repair. (can't dispute that printed frames do cost less)

More to come as they are made. Keep checking back to see the current updates.

UPDATE Jan 7th, 2016
The AG Silpheed is modular frame, where different arms and top frames can be added to the bottom base. Currently I have built and tested 4", 5" and 6" configurations. I have only uploaded the 4" arms and the V6 Rollcage top frame... but more files will be uploaded as they are tested and developed.

The current uploaded 4" AG Silpheed frame is so much fun to fly... and quite durable in crashes. I've been flying it in the indoor race track all winter - and goes up against many carbon fiber frames.

UPDATE Jan 31st
Major update! Really excited to share these...
2 new rollcage designs : you can now mount a gopro, mobius or other recording cameras
new arms to support 5" and 6" props. (the speeds that are achieved with 5" and 6" are so great - the chance of breaking an arm is significantly higher.. but hey, just print some more arms :) don't forget to tape up your arms, so you keep the arms from ripping off - you don't want ripped out motor wires! Trust me, that's painful.
If you want an alternative protective housing for your GoPro, please print ours!
