This is a easy-printing housing for an ELP stereo webcam, which comes as a bare board with fisheye lenses: the ELP-960P2CAM-L180
It accepts a 1/4"-20 nut in the bottom to allow tripod mounting: you may want to glue the nut in place (I used hot-melt glue).
I initially intended for this to be the bottom part of a two-piece complete enclosure, but it works well enough on its own that I'm using it like this for now.
Some photos show an older revision - latest one has rounded bottom edges, extended retention tabs on the top, and a groove for the "camera on" LED light to be reflected and transmitted through from the back of the camera to the front.
(Print does not include the actual tripod shown in one of the photos.)
Software
Designed in SolveSpace 3.0 (currently unreleased, master branch used.) SolveSpace is a lightweight, fast, parametric 3D CAD system, that is free, open-source, and cross-platform. Highly recommended. Source for this object is in the zip file - housing-bottom-lightgroove3.slvs is the recommended file. (Looks like it might be rejected by MyMiniFactory? What a bummer - hard to modify a model without the sources. The same model is on Thingiverse with the sources.) The others are either components (model of the camera, model of a nut) or earlier versions. I used PrusaSlicer to "repair" the exported STL to meet MyMiniFactory's software check - it prints just fine, not sure what's wrong with the STL.
This is designed for easy printability, just lay it flat on its back when slicing. No overhangs exceed 45 degrees (that's why the tripod hole is a teardrop - thanks, Maker's Muse, for that idea!). I printed with a brim, but it's flat enough it probably doesn't even need that if you have good adhesion. I used PET-G because I had it in the printer, I doubt it matters what filament you use.
No support material needed, prints in about an hour for me.
Adding tripod mount
At least in the USA, 1/4"-20 (quarter inch diameter, 20 threads per inch) is the standard for tripod mounts. I think it's the same elsewhere too, but it might be a little harder to find that size of nut.
Drop the nut in "point-down" (the left and right sides of the nut should be parallel with the left and right sides of the enclosure), then seal it in somehow: tape or glue should work. I used hot glue (hot-melt glue) which worked great.
LED
You might want to put a little hot melt glue in the groove for the activity LED to act as a lightguide. Not required, but can make it look a little easier to see.
