Stand for Dahua eyeball-style IP cameras

This is a very quick and dirty stand to allow an "eyeball" style camera, specifically a Dahua 3-series one, stand on a table or other flat surface, but higher than just sitting on the surface.  This allows the camera to be placed indoors looking out a window, without permanently mounting it, and getting the camera higher up and able to tilt further down, to get a less obstructed view.  It is not suitable for permanent mounting or horizontal use as the outer walls are too thin.

I doubt this model will be of any use to anyone, but perhaps it can serve as a starting point for a custom model specific to someone else's use case.

Note that to minimise filament use, the outer walls are very thin.  This is not a problem but it means they will crack on the layer lines if you squeeze it too hard.  You may wish to make the outer wall thicker if you expect it to be handled.  I left it thin because once it's in position I'm not touching it again.  It's much worse if printed in 0.28mm draft mode, 0.2mm balanced does make the layer lines stronger.

There's a section in the middle that can be filled with weights (e.g. sand) to provide stability, however as it turned out it's not as unstable as I expected so I didn't have to fill it with anything.

I used 12mm M3 screws to attach the camera base to the printed object.  You may have to enlarge the screw holes if you wish to use larger screws.

The model is 145mm tall from the base to the lowest part of the opening, but this can be changed in the OpenSCAD file by editing one variable near the top if you wish to make it a different height.  The model is designed for 105.7mm outer diameter base on the camera with screw holes 70mm apart, however this can be changed by messing around with the OpenSCAD code per the comments within.
