If it looks like a rats nest of wires, it is!
This was my very first print project I chose after getting into the 3d printing hobby, so don't judge the quality too much =)
I'm using the suggested motors which fit perfect without any additional needed restraining hardware. I wrote a small program on an Arduino Uno clone and used the cheap original ($8) Adafruit motor shield, a buck converter to drop the voltage from the 12v 3S LIPO batteries I had kicking around down to 8 volts (1 volt over recommended voltage for the motors, but seem to be doing fine), a wireless FPV cam I salvaged off an old octocopter build I had years ago and am running it with my cheap hobbyking turnigy radio.

After printing, the pieces all fit together like a dream, and glued together nicely. It's been abused by my 2.5 year old and his dinosaurs (half the reason I built it)

I'm working on a few modifications as we speak including a snap on rotating turret add on for the original, and a "double" version that can hold more electronics and still maintain the slick low profile made by the original designer. My 2 year old loves driving it (with my help) under his bed to find his hiding DINOSAURS! through the camera.

This thing is great!!! I'd have a dozen more if I could use them!

PETG is great stuff for this type of build. Strong and flexible. 245 at the nozzle, then 90 bed temp, no fan initial layer, 85 degrees bed and 100% fan for the rest of the print.
