About this 3D model

I organically designed this pen holder to mount onto the frame surrounding my desk. But I have made some changes to the design so others can use it as well. I made two different models with different means of mounting. One that is mounted by zip-ties and the other mounted by screws. It holds 13 pencils or pencils in each unit. The pen holder is designed to lean off the wall at a 35-degree angle. So they can be stacked on top of each other and have easier access to the pens. Let me know what you think, I can always edit the files and re-upload them if I get good constructive criticism.
