Works very well, thx

Printed 0.2mm layer height PETG. The unsupported overhangs required a bit of clean up but they're hidden after installation so form wasn't a consideration. Not as secure as a plate attachment, but good enough for my purposes. I love that for a three corner joint the required number of parts is 4 (this plus three screws) versus using brackets which would be at least twice as many parts with the number of screws and nuts. Thank you! (edited)
