3D Print Quad

[Bad Raven]

OK, so I decided to make a 3d printed frame quad, one designed to be heavier than usual in order to be more easily flown in the swirling breezes in my garden that result from the surrounding trees, etc, and stronger to absorb the intended more loony speed circuit use.

Looking on Thingiverse, I had quite a struggle to find suitable, and in the end it was pretty obvious that I'd have to adapt what was around or take the longer route and completely scratch build.

Just before giving up I found "The Onion", a roughly 100mm frame, which looked a possibility. After downloading it was obvious that there were issues.

Though intended for a 20mm stack, what I had didn't fit, and neither would the 1106 Emax motors. Also holes for the various exits like the power wires were wrongly sized and poorly placed (for my hardware).

Also I wanted the camera a little higher than intended, but it looked doo-able and faster than designing it all.

My Hardware :-

Eachine "Anniversay" 20mm Stack (extremely similar to Aurora 90 stack). Betaflight.

Emax 1106 4500kV Motors, 2030 Tri blades.

Eachine AIO Camera/VTX

Aurora Spare LED board (four LED, right size for between arms)

I had to scale up the frame, adjust virtually every access hole/port, enlarge the motor recess.

Although I scaled it up to 110%, I still had to ease the motor recesses, and open lots of holes. And make a "lid" to protect the top layer of the stack (with hole for Buzzer).

The results were pretty much all I desired, it came out to 81g sans battery, 127g with 650mAh 75C 2S ACEHE (XT30 connection).

It is very positive, going where its put, being really stable in all orientations with a very good turn of speed.

Made from ESun PLA, it has been dropped twice from waist high onto concrete, with no damage, and after clipping pool noodle hoops while flat out it cartwheeled down the crazy paved path, but again was unmarked, only a bent VTX antenna.

I'm now about to build a lightweight thinned down version in PETG for 7500kV motors with the same stack.
