I used Sainsmart TPU with some supports in the right places (paint on supports) - easily removable.
The second model uploaded is for the M10 GPU and I've updated the model for easy antenna Install / removal. I made a cut at the back of the model so you can easily put the cables in & a 3mm hole so you can cable tie it after the cables are installed.
I also added the improved one with hole / cut for the M.8 now.
