The battery/vibe tray from RCExplorer was flimsy with PLA. Would be fine with G10 or carbon fiber, but when printed with PLA, my go pro would flex and bounce around a lot while FPV. My solution was to thicken the plate to about triple the original thickness. I also moved the triangle to the other side, I like to have the wire go UNDER the tray, so that the top is flat for my battery. I had a 3.15mm carbon rod sitting around so I also added a 3.2mm hole near the front to insert a carbon fiber rod for additional rigidity.Printed this with a honeycomb 20% infill, 3 layers on top/bottom.
