Ikea Ekby Valter Shelf Brackets-ish

I couldn't find them anymore at Ikea (probably discontinued) so I made similar ones. First time publishing a model, still figuring out the 3D model application (made with Plasticity).

They are a bit smaller at the extremities to be able to fit on my printer bed (220x220mm). Other than that change, they are the same dimensions.

I'm not sure of the maximum strength they can hold vs the wood ones, but a shelf with light stuff on it holds perfectly.
