Bamboo wall shelf

I wanted to make custom shelves for my walls, and came up with the idea of using 3D printed parts, metal screws and bamboo sticks. Three different materials! Fun!https://www.amazon.com/gp/product/B0B61SJK6V I used those dowel rods. Hammered them into the 3D printed parts with a rubber mallet, and perfect. No glue needed!
