I've got a bunch of temperature sensors, voltage meters. etc that use a 45mm x 26mm form factor. This case holds them at an adjustable angle. Use a 2mm rod (or a long finish nail) to connect the base to the case, forming a hinge. The base has a clip for holding a temperature probe. There's a hole in the back of the case for the probe or wiring to exit. A small speaker grill is over where one of my meters had a small buzzer. The two slots on the back of the case allow you to stick a screwdriver in to remove the meter from the case.
