Balcony, Porch, or Deck Shelf Bracket

thingiverse

This is a bracket that when used with a scrap plank of wood, will give you a shelf to be used on your balcony - Perfect for putting your pint down on, while you have some summer porch beers. This was designed to fit a 37mm wide by 76mm tall railing, which is farily standard in my area. The actual dimensions of the design are 39mm wide by 76mm - There's a 2mm clearance to allow for easy fitment. There's a 100mm (approx 4") ledge for your wood board to sit on, then it's held by a tapered head screw horizontally, as well as a single screw underneath. I took a scrap piece of 5" wood board off a shipping crate to make the shelf in the pictures. It's fairly sturdy, I put a 10lb plate on it to test, and it held no problem. F3D file included if you want to modify it.
