Press fits over the two central press nuts of the Big Brainer FPV racing frame, isolating them elegantly from the ESC.

This holds on quite well, and if it were to move in a crash it would still be prevented from coming out by the ESC.

I'm using 0.5mm TPU spacers on top of stainless steel press nuts. This minimises stack height without the Foxeer 60A Slim capacitors resting on the press nut cap.

Printed at 100% infill, 0.1mm layer height.
