For a full explanation of how to build these shelves, you can check out my Instructables at this link: Custom Hexagon Shelves
Make your own custom hexagon shelves! I wanted to build a set of strong, fun shelves for our home, so I decided to make my own hexagon shelves. Each piece was printed with 3 walls with a 0.4 mm nozzle 20% infill to make the vertical walls solid and as strong as possible without printing the parts completely solid.
These connectors are designed to hold 1" thick dimensional lumber, though you may need to scale them up or down slightly to fit your specific materials. With a tiny bit of sanding, these parts had a snug fit on unfinished 1" x 8" premium pine boards. Each branch of the connectors also has a countersink hole sized to fit a #6 wood screw.
As you design your shelf, you will need to print a connector for the front and back of each corner. In the finished shelf, I used 16 of the triple connectors and 24 of the double connectors, which used a total of about 1 kg of filament.
My favorite part about this style of shelf is that you can use two basic parts and some wood to design whatever hexagonal pattern you want, so have fun with it! Good luck!
Note: The original files were exported in centimeters, which caused the parts to be off by a factor of 10 in most slicers. I've replaced those files with new ones exported in millimeters. Everything should be correct now, and I apologize for the mistake!
Update: Added a part sized for 20 mm wood based on a request. They are sized for exactly 20 mm, so you may need to sand the boards or scale the part up a tiny bit to make sure everything fits correctly. Enjoy!
