Iris aperture

thingiverse

To protest Makerbot's closed sources, I will soon remove this model from Thingiverse; you can find it at Cubehero via https://tinyurl.com/pt3t4fb. A semi-parametric aperture designed in SolidWorks for practice and inspired by other irising boxes is featured here. Although untested on a 3D printer, the assembly fits well with tight tolerances except for sliding leaves. The open aperture doesn't leave an empty circle to improve aesthetics. To assemble, print one base ring, five leaves, and five pins. Attach the leaves to the base ring with slots facing upwards, followed by placing the top ring over both. Insert pins into the base ring's holes using CA glue for securement. Leaves may be removable but untested. Twist rings to open and close leaves.
