I'm making a Wi-Fi clock using a Pico W and 60 LEDs on a neopixel strip. 

The model is intended to hold the led strip in the lens, wires pass through a hole in the housing to a Pico W that gets trapped between the housing and the back cover. 4 M3 screws go into the housing front to thread into the back cover, then 2 more go in the back to thread into the lens. Hand hanging hole on the back.
