A friend of mine Derek will be battle testing this 10mm version of the hanger in black abs plastic.
I added, probably unnecessarily, some holes for material saving and don't think I'll be bothering in the future. If I keep them I'll be rotating them so no support structures are within the 45 degree angle I've set in the software. I can change the angle it that will make it use supports from 45 to something else but I don't think it's worth the hassle.
If I decide to make it available as a stl download it will only be from here, so don't expect it to be on any free 3d download sites.
