The Plus Shelf by [shurly] aims to make building your own shelves a little easier with a 3D printed bracket. These connectors aren’t just sitting flush against the wood of the shelf.

In the attached video, I show how I built these little support units in TinkerCAD and 3D printed them, and how they will support three-quarter-inch plywood shelves and give me more shelf space.

Wheelson in particular used 3D printing in a huge ... Both builds feature 3D printed GPU brackets, ... The next option up is going with an off-the-shelf solution such as the SAGE or MNPCTech's ...

He wanted shelf brackets that “look cool.” Given the relative orientation of the layers versus the loads, the dollar store brackets might even be stronger than these, but would not “look cool” ...
