This is my custom Raspberry Pi B+ Case. I've downloaded & tried two different cases an none of them were what I've expected. So in the end I made my own.
There are two different top parts. One with fan, the other without.
The heat sink is 10mm high and 30mm wide. I've cut it in half so every piece is about 30x15mm.
The screws for the case are 8 pieces 3x12 self tapping screws. First place the Raspberry in the lower part, then use the 4 round supports to fix it with the smaller screws inside the lower part. (Maybe you need pliers to hold the round supports when tightening the screws)
The ones for the fan are 4 pieces M4x12 machine screws.
