Raspberry Pi for Geeetech A20M

I am using the Anycubic i3 MEGA Raspberry Pi case for OctoPrint (https://www.thingiverse.com/thing:2754779) by FischC for my Anicubic printer and am very content with it. I think that he has done a very good job - thank you very much for your work.

So I wanted to use it with my Geeetech, too. That's why I started to design a completely new holder for his perfect case. As a growing project of mine, I've made some versions which you can download. They all have to be at the left side of the printer and are fastened with one original sliding-block-nut and one selfmade one (http://www.thingiverse.com/thing:3470041), constructed by myself.
V1 is a holder for the Raspberry Pi without a camera.
V2 is a holder for the Rasperry Pi and a clip-camera. By using it I realized, that my camera is a little bit too close for sharp pictures.
V3 solved this problem because I designed it a little bit longer. Then I saw that the bed is very close to the holder and wanted to make some more distance.
