Raised bed garden corner bracket

Remix of https://www.thingiverse.com/thing:967925, but for 2x4s.  I'm printing it in PETG at .20 with 15% infill.  Use 1" diameter PVC to combine the pieces.  Printing 8 at a time, you can knock out two sets in less 4 days of printing.  The assembled pieces will make four layers to create a bed 14" in height.
