RS232 add-on for the badBrick model B RaspberryPi case

This snaps on top of the badBrick model B RaspberryPi case to hold a level-converter for RS232 so the 9-pin D connector can be securely held to the RaspberryPi for easy connection and disconnection. This makes the RaspberryPi significantly more useful as a micro-computer for dedicated devices (I use one for interfacing to a Amateur Radio transceiver via the UART serial built into the RaspberryPi and a USB sound-card)
NOTE: this is the serial adapter that I designed this to fit.
