DMMCheck Case

(Please excuse the poor quality of the print in the photos. I was using draft mode on a printer that is in need of calibration, but it's good enough for my workbench!)

DMMCheck is a very nice high precision voltage and resistance standard reference for use in calibrating multimeters. You can find them at voltagestandard.com.

This case holds and protects the DMMCheck r3 board. I don't know if it fits other board revisions, but it seems likely. The board is attached to the base using M3x4 screws, and there is room underneath to hold the calibration page that comes with the board.

UPDATE: The original lid is intentionally a loose fit. I've added an alternate lid for those who want a tighter fit.
