Hobby King Fiberglass 450 Quad Battery Cradle

thingiverse

This is a battery cradle for the Hobby King Q450 v3 quad frame. It's made by Diatone. http://www.hobbyking.com/hobbyking/store/__54664__Q450_V3_Glass_Fiber_Quadcopter_Frame_450mm_Integrated_PCB_Version_US_Warehouse_.html The bottom PCB doesn't allow for securing the battery very well and the opening doesn't allow for a very big battery either. So, I came up with this. It's pretty straightforward and goes together with M2.5 12mm and 20mm screws. This allows the battery to be mounted very low in the frame. The SM450 LG part is designed to be printed with something flexible, like NinjaFlex, but one could print it with other materials. Meant to be sacraficial. The center piece comes with built in support since the center arch doesn't come out well otherwise.
