Drone/FPV battery tray hooks

These hooks will go on a HobbyKing S600 Quadcopter but can go on any other similarly configured drone. My measured distances are 59mm between rods and 24mm hole distance. This is not normal, so you would have to slightly adjust the openSCAD file I have provided if yours features the usual 60mm rod spacing and the 23mm hole distance.
You can also adjust the depth of the hooks to adapt for lighter or heavier batteries. Currently the STL has 12mm depth.
The upper shape is a parabola, contact me
