Customizable flag pole holder

A fully customizable wall mounted flag pole holder.
adjust the with of the hole, the angle, the length, the size of the ground plate, etc.

If the customizer on thingiverse doesn't work, download the SCAD file and open it in openSCAD to customize it.

(update march 27 2023: The customizer does not work correctly if I try to customize this on thingiverse. The labels are visible, but you cannot change values. So for now the only way to customize this is in openSCAD)

I tried to make it as reliable as possibly, but please check the model after customizing it. It's very easy to create something that is ugly and/or instantly breaks.
