This is a pistol-grip-style housing for a UV light meter for use in Wet Plate Collodion photography. It houses:

• Nokia 5110 LCD
• Trigger button
• Arduino Pro Mini
• 3 light sensors
• RF transmitter
• 9v battery

The two halves are held together with screws for the upper section and a screw-on cap for the lower section which houses the 9v battery.

Modeled in OpenScad. Apologies for the poor quality of the code.

Note on the screw cap: scale it up a bit when you print it (I printed three: 1.0, 1.05, 1.1. the 1.1 fits the best).
