Customizable mounting bracket for post, rod or dowel

I needed a bracket to mount a bird house on top of a 1 & 1/4" dowel, so I designed this customizable component that printed really nicely in PLA on my Bambulab A1. I thought other people might have use for this kind of Thing, too, so here you go.

It's highly unlikely that you need the exact same dimensions I did, so open the customizer and you'll be able the change the following parameters:
* height, internal radius and thickness of the sleeve
* height, length and thickness of the angled braces
* width, length and thickness of the horizontal flanges
* whether or not there are screw holes in the sleeve and flanges, along with their radii and positions

If there's interest, I may also add the option to countersink the screw holes.
