Open Door Hanger for Quad Racing Gate

This is a door hanger for my Quad Racing Gate ( https://www.thingiverse.com/thing:3423366 ). I made it for a door thickness of 1-5/16" (approx 34.5mm) to 1-3/4" (approx 45mm) as they were the narrowest and the thickest doors I have here. I put 6 holes in just to give a choice of how you want to mount it as you could use it for a table, a shelf, etc.

It needs a 3mm bolt that you self tap (by screwing it through the hole). In use, you only want to hand tighten the bolt to simply make the hange
