I was looking for a filament shelf bracket that would let me use oak closet rods that are 1-5/16 in in diameter. I didn't find one I liked and it seemed like a good first 3d model in my endeavors to teach myself 3d. I ran into some things I wanted to do but don't know how yet, but I'm pretty happy with the result. I had to snip the tips off of the drywall anchors because the concrete wall on the other side was too close to allow them to be fully inserted otherwise.
