What you get will be digital files, including PDF, DWG, STEP, 3DPDF formats. What you get is not a physical product. But you can manufacture this products with these files. Note: Digital goods cannot be returned.

Parts are designed towards to manufacturing purpose, and the functional unit can be used on industrial products. If you plan to 3d print these parts, we cannot ensure the mechanism will work well, because it is not designed for 3d printing. But you can try to 3d print with resin material and have a test(maybe need some hand work).I test the mechanism with a FDM 3d printer(I made some change on the 3d model before printing). But I don't provide 3d printing version models.

The whole mechanism can be used as a functional unit. When you rotate the “Drive Gear” or the “Ring” , the blades in the center hole open or close gradually. It is similar to a camera aperture or iris diaphragm. A motor can be used to drive the mechanism. The center hole is 70 mm.

The “Drive Gear”(Part D70.002TY2) is optional. You can use any gear as driving gear as long as its gear teeth’s parameter is the same to the table in the drawing.

Ignore the FBX and OBJ format files, they are only used to meet the platform’s requirement.
