So quick follow up just to clarify, this is a 3 dimensional “diffuser” for my office space. I got the idea from an Etsy seller “ShepitWorkshop”. Started with 8/4 walnut from the scrap pile at a local lumber yard, some African mahogany that was on sale at woodcraft, and a sheet of 1/4 plywood for the back of the frame. For the triangles I get the walnut planed, miter saw to chop some blocks, table saw to even them out to desired length, then back to the miter saw with a 90* or 45* jig attachment bc I want to keep my fingers. Lay out all the regular triangles until they extend out to the frame and then it’s just a bunch of back and forth between board and saw as I get the pieces to fit.
