This is a carriage for mounting a Raspberry Pi Model B board in a case. It uses edge clips to attach the board.
Prints on a Makerbot with default settings, no support or raft required. The SD card slot has a built-in support which needs to be cut out with a sharp blade.
base.scad is the source for the carriage, and it depends on pibase.scad which provides a geometric model of the Raspberry Pi board plus clearance volumes that are used to create the openings for the ports.
This is part of the Gaugette Time Clock documented here: http://guy.carpenter.id.au/gaugette/blog/2013/02/03/raspberry-pi-time-clock/
The scad file for the OLED bezel is included here too.
