125mm micro brushless

My first design of my own. Concept to start, basically I want to try and keep it clean on top. Made openings underneath for 6A ESC's, a 20x20 mounting holes for piko/femto, trying to route everything underneath. motors are spaced for 1103's.. going to print it tonight and see how it looks.

Any suggestions on a battery placement would be cool. I was somewhat considering using 4 "tiny whoop" type batteries and finding a spot for each on each arm... then wiring 2 in series and 2 in parallel for a 400ish mah 2s setup..
