Corner brackets for d12 / dodecahedron for 1/8" plywood

thingiverse

My wife wanted a d12 calendar made from 1/8" plywood (with the months added using a Glowforge.) It took me several iterations, but this is what I've finally come up with and I'm pretty pleased with it. It takes 20 brackets for the full dodecahedron. In this image, each pentagon is about 1.3" per side. It was a little tricky getting the last three brackets on, but I was able to open it up a little and then finally get them all on. :D And it looks pretty good! The brackets are specifically oriented so that the side on the bottom side has a slightly larger slot than the other two sides. This is to compensate for the slight shrinking that that side has with my Ender 3. I used the "Lay Flat" option in my slicer (Cura) when setting these up. (I printed 4 sets of 5 at a time.) The settings below are the ones that I used for this specific print. (Rafts and supports.)
