Parametric modular pole mount piece

(If you're having trouble with Customizer, download OpenSCAD to edit this and adjust all parameters, it's free and less glitchy)

I needed a modular piece I could print to mount all the rubber duckies I got from work, as I didn't want them just sprawled around everywhere. I made the original model in Blender, but then decided to use the same model to learn SCAD.

You could use this to mount things that can use a single pole for affixation, mounting multiple of them if needed by chaining the pieces together.
