DJI F450 bottom plate

This is a bottom plate that will fit a DJI F450 with the flame wheel arms. It is only 2mm thick, so very light. Version 3 is 3mm thick and much stronger. Here is a top plate by dennisbaldwin http://www.thingiverse.com/thing:60076 that goes very well with the bottom plate and that I'm currently using. Any comments and suggestions welcome.
