Externally mounted contact sensor housing for metal mailbox

Hello, Sam_Bam.
I took you up on your suggestion and visited etsy.com and searched in idea xtruder. I found lots of stuff, but nothing close to an upside-down enclosure with a flat spring keeper for a contact sensor.
Of the STL files, I offered in my last dozen or more post only a few were similar in idea xtruder.
Most of my cameras are fixed and the three dome cameras that are pannable and zoomable are rarely moved.
I like the DogLeg style camera mount because it is simple and fixed. Getting a custom DogLeg camera mount for your particular aiming needs a lot of math or the harnessing of the spatial environment by hands-on methods, see Make a Simple Dog-Leg Camera Bracket No math no trig no vectors no protractors no calculations.
I have completed a spreadsheet wherein basic camera aim requirements, camera geometry, and bracket parameters are input, and an STL structured document is automatically generated. The structure file is copied and saved to a text file with a name of your choice and the .stl extension. Ready to load into your 3D (or the library’s) printer. You may be thinking “do I have to look up the camera geometry” ? No, you don’t, in the spreadsheet, you input the camera type, and the spreadsheet loads all of the pertinent information. You only input four items, horizontal aim angle, vertical aim angle, bracket thickness, and the wall plate length.

Here is the link to the spreadsheet: DogLeg 3D Standup to STL 071921.xlsx

The pictures below show a library print of the spreadsheet output with specific aim and geometry requirements.

The base was removed to gain access to the 1/4"x20 threaded mounting hole. The base was replaced with a 6mm shim plate and a Nylon screw. This reduces weight and makes for a stable camera mount.

Other projects are in the works.
