Shelf Brackets

This is a set of shelf brackets I designed to be organizers for my kitchen cabinet. The openings in the top fit 1/4x4 inch boards nominal size, actual size of opening is 1/4x3.5
I used a rubber mallet to get them in but it's a tight squeeze so you could make the opening slightly bigger if you like. They're fairly sturdy though they do take a while to print each pair (5-10 hours depending on print settings)

Screws are #6x3/4 inch, they stick out slightly over the top as you can see in the photos but it's not too bad.

*I highly recommend drilling small pilot holes in the wood when the boards are inserted because they do have a tendency to crack otherwise.
