About this 3D model

This the replacememt part for the DJI PHANTOM 3 Gimbal mounting plate. I built it for a friend who's drone crashed. it is modeled based on measurements from the broken part and the actual drone. I have done both a solid and a 15% Hex infill on this part and i have listed estimated weights based on the the model volume in the images. i have not weighed the physical sample as i do not have a scale that measures such a small amount. if any one who prints these parts is able to verify my estimates please comment, it will be greatly apprecitated.
