New Case for Raspi-Zero-2W

#RasPi Zero-2-W Case - simple

If running in normal mode (not overclocked), the Pi-Zero-2W doesn't need a heat-sink, since its temperature does not go much higher than about 40°C.
- This simple case may protect the electronics aginst short circuits
- it comes with a Pins-"Flap-Lid", to handle the 2 rows of his 40 IO-pins.

###Possible add-on's:
- a Raspi-Off Button. (See my instruction on Github: [RasPi-automated-On-Off-circuit](https://github.com/nlohr1/RasPi-automated-On-Off-circuit)), for this simple Off-Button you need only the button and the script-file for it.

###Included:
- stl-file of the Pi-Zero-2W
- stl-file of a Micro-SD-Card

**Hint**: Pi-Zero's lacks of a power signal led to indicate if they are "alive" or not. If you connect the device with a cheap (broken) SD-Card, it *may appear* "dead" -
but its only because the *communication LED* is off - it's not a dead Pi. You can prove this, connecting the Pi's USB-Micro-Jack (not the Power-Jack) -without SD-C
