This is a case for the Kimdrox Adjustable Voltage Regulator found on amazon. It will likely work for all the other brand voltage regulators of similar design found around the web. The board has 2mm clearance under it. Its difficult to see in the pictures but there are built in standoffs in the corners and the pins fit in the PCB holes. The lid will need a bit of carving to fit. I included the 123D file as well. If you are looking for a more complex design check out http://www.thingiverse.com/thing:942939 The voltage regulator can be found here: http://www.amazon.com/gp/product/B00L6VSXEC?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00&pldnSite=1The lid will need three notches carved in the lid to fit. An exacto knife will do this nicely.
