About this Product
This is the lower shield of my case for Raspberry Pi computer (see www.shapeways.com/model/486999/raspberry-pi-case-1-0.html).
It is intended mainly for replacement in case of damage.
You can also order it with the related top part (www.shapeways.com/model/720303/raspberry-pi-case-1-0-top.html) if you just want a 2 colour case.
If you need an enclosure for your Raspberry Pi computer board, you should choose the whole case.
