Diatone Caddx Turtle V2 Back Pack

So I wanted to put a Caddx Turtle V2 on to my Diatone GT-M515, but of course there is no space for it inside the frame, I looked on here and no one had done it yet, so that meant a trip into SketchUp. Here is the result. It works, I'm not happy with the look of the top piece and I will be designing a V2, I've just got a copy of Fusion 360, so I will be able to do more lol
It is printed in PLA and I printed it in orange as it has the biggest contrast with the green of the grass and bushes, hence it should be easier to find when I crash lol.

I've put up the SketchUp file so that anyone can have a go at changing it for the better, but if you want to sell this then I ask that you contact me first please.

If you would like one and don't have a printer then please contact me and I'll print you one off, for a very small fee and you cover postage.

Ok I've uploaded a copy of the top part without the mounting holes as people were asking for a copy to mount VTX's i
