This is a remix of the case from Leo_N but i made it completly from scatch... (cause editing a stl file is a pain in the a..)
It's designed to be attached to the side of the AM8 frame.
I added 3 versions of the case (with a SD card reader, a µSD card reader and no card reader at all).
It's designed to be sturdy as it will be stressed by the user :)
I encouraged you to attache it to both side of the frame but the top side is ok.
To do so you'll need 2-4 M5 screws.
You'll need to disassemble the SD/µSD reader to make it fit to the case. It can be easely done by uncliping the reader's case (see picture) and fix it with some glue (i used hot glue, it worked fine).
I'ms using this wonderful knob made by JPgxuAHFR22RQo (what a name !!) https://www.thingiverse.com/thing:1734712
This is a thing in progress so i'm waiting for you comments :)
