About this 3D model

This is something I'm very proud of. It was one in fact on a list of the first ideas I had when I decided to print in 3D. Its an organizer for spray paint caps. I've been working with spray paint for a while now, and something I've always wanted was a way to organize my caps so i didn't have to hunt them down in a bag or a box. It takes a lot of time and effort. So I thought I could just figure out a way to hold them together into a clip or something. I ended up with this design. I liked it because I managed to accomplish my goal using only two unique parts, and I went through seven revisions of this project before I was happy with the fit and function, but pretty happy with the overall design so far. So let me know what you guys think.
