Summary

in case you have 24mm high left in your frame this is the solution to remove the esc from the arms.
I made the slot little wider so the esc can be placed with a drop of liquide tape in there to dampen them a little.
Remember, KISS ESC telemetry can be connected together and just 1 wire to the FC.
There are two versions with esc centred and off center whatever you prefer.
Its a work in progress, future modification are possible, feel free to print, try and share pictures.
Have fun, fly fast and crash hard :-)
