Looking at parts.. would this FC be what you recommend?  F3 Evo 6 axis brushed?  Also what motors?

It was just the FC I thought of.
If you tolerate some hicks an glitches the Scisky is very easy to work with(only 10 wires to solder).
All 8.5x20mm Hubsan-style motors will do, but I think Racerstar gives you a lot for the money ...
If you wish to modify the files, then it is to seal holes that are not used.
Creating 8.5mm holes on the arms (remember that the motor must be turned slightly angled so you minimizing the effect of turbulence).
Maybe combine front arms and feet, so you can push the motor right in(and for better protection).
Adjust the hole for usb-contact.
Make a proper seat for the FC.
The holes in the base for fixing the middle-part need to be only 5mm(to make room for the FC)
I didn´t know if it would take off, but I'm keeping the altitude with 50% throttle.
For FPV, maybe a Eachine TX01 mounted upside down will fit?...
I use screws that are intended for plastic
4 pcs 6x1.4 to secure the middle to the base
6 pcs 9x1.4 for attaching the rear arms, the top front and arms

Love the mini Mavic, must do one myself. I can probably transport the electronics from my Hubsan.

There are 2000mah 3.7v cells available, that should give you a decent runtime.

triafgg: I was worried about the weight, but it was no problem. Hubsan electronics is of good quality.
Within 3D printing, you must know the following: Size you want times 100 divided by the size you have. In this way you get the size you want in percent of the starting point.

tjkim93: Yes, it´s possible to fold the legs...but only 70% because of the size of the motors.
Hmmm... do not understand what you're talking about...brushed... what?

Your first version is brushed motor with 1S(cell) 3.7V battery.
8.5x20mm Hubsan-style motors are brushed motors. (brushed coreless motors)

You seemed to build brushless motor version already.
You ill use 2S(cell) 7.4V battery?

Got my mini Mavic finished.

Flies really stable. I'll upload some video when I have a helper to film.

My conclusion
Although I was quite pleased with the first version of my Brushed MiniMavic, there were a few things I would like to change.
Battery: I wanted greater capacity without increasing the size I had on the Mavic body too much.
Solution: As I mentioned earlier, I adjusted the size of the files to 42.5% of full size on version 3.1 F3 files in Cura.  I now used 53% on the height(Z) of the middle, nose and gimbal holder parts(X / Y still 42.5%).
I then cut the sides on the middle part to fit a 9.7 X 24 X 44mm (1S 750mAh Syma X5C style) battery.

Colors: Change the color of the front, to more easily determine the direction when flying.
Solution: Printed the top front cover and gimbal holder in Black ABS.

Motors: As I have placed the motors, you can not fold the model 100% together. I had the idea that front motors should replace the front legs, so that's why it became like this.
On the next model, I will choose the same solution as triafgg for the location of the motors.

If I could modify 3d files, I would have:
Changed arms to fit 8.5mm motors
Made it possible to change motors without having to pull the wires through holes in the arm and base section.
Removed unused holes in the bottom of the base section

Parts I've used:
Micro Scisky 32bits Brushed FC
Hubsan X4 style 8.5X20mm motors
Turnigy nano-tech 1S 750mAh 70C
Eachine 3-Blade Props for 8.5x20mm Coreless Motor
If it ain't broke, don't fix it!
