About this 3D model

I will soon be pulling this off of Thingiverse, in protest of Makerbot's closed sources. You can find it at Cubehero: https://tinyurl.com/pt3t4fb A semi-parametric aperture that I drew in SolidWorks to practice modeling. Based off of, but not copying from, several other irising boxes. As I don't have access to a (FFF) 3D printer, I have not tested it, but the assembly fits together and moves quite well. I left reasonable tolerance on every joint except for the sliding among leaves, which shouldn't be a problem. When the aperture is open, it does not leave an entirely empty circle in the middle -- I sacrificed that to make it look better as it opens.
