Geometric Shelf Brackets

I made these brackets as part of a kitty highway project. They are reasonably strong, but can be made very strong with different wall and infill settings. The settings in the .3mf I used were more than enough for this wooden shelf for our two cats. A long screwdriver or extension is needed to screw in two of the screws, and they are designed to accommodate up to 1/4" or 6mm mounting screws, 2 to the wall and 2 to the shelf. There are 3 sizes included. Enjoy!
