Mechanical Iris

thingiverse

This is a straightforward mechanical iris created to be quickly printed in 3D. To create your own, you will need to print one base, one ring, five blades, and five pins. The pins may require rotation - they are designed to be printed with the larger diameter at the base. This design is still a work in progress with plans to improve it by reducing friction and making assembly easier. It was created to be thin for faster printing, but this can make it difficult to grip and operate, especially on printers that produce a rougher surface finish. UPDATE: The 0.25 mm tolerance in the .stl files worked well on Tinkerine DittoPro, but not as well on a Prusa I3. There is a parameter in the Fusion 360 file that can be adjusted to suit your printer's specifications. Note: Photos display the first prototype of this design. Print Settings: * Printer Brand: Tinkertine Studio Printer: Ditto + Rafts: No Supports: No Resolution: 0.2 mm Infill: 20% Notes: * PLA was printed at 220C with a speed of 50 mm/s. * This printer used was the DittoPro, not the Ditto + model.
