Raspberry Pi 3 + Raid 1 (2x2.5" disk room) case - parametric version

**UPDATE Apr 13, 2019:**
- fixed the LED hole place
- added a short version in the SCAD file (shortened version cut-out at the rear)

**Description**
This is a parametric version (using openscad) of my [previous case](https://www.thingiverse.com/thing:3447161) which had several weaknesses.
This version is longer so that internal cables can fit in the box, it is also higher so that the wires between the fan and the rasp can also fit.

Only one disk is installed on the photos (cause I have only one connector at the moment)

The hole at the rear of the bottom box (long version) allows to pass an Ethernet cable or an external USB hub.

You can use this kind of [connector](https://fr.aliexpress.com/item/USB-3-0-to-Sata-adapter-converter-cable-7pin-sataIII-to-USB3-0-adapters-for/32830988939.html?spm=a2g0s.9042311.0.0.27426c37xWGQgn) between the 2 disks and the Pi.
