Pollin Roulette case enclosure with 9V battery holder

I created a nice enclosure for the roulette PCB electronics kit from Pollin (No. 810 163 - www.pollin.de).
You will need an additional 9V battery and a 9V clip to get the kit up and running in that enclosure.

The 9V battery slips in a small rail which is under the PCB.
Small posts in the corners keep the correct distance from the PCB.
A little cutout lets the wire slip over the edge to the underlying 9V battery.

Print at a low feed rate so that the PCB does not sit too tight in there.
