Part are designed for 3d printing. It is best to use resin material, and some hand work is necessary to make it work well.
The parts should be smooth enough,so usually you need to sand some areas.
If you use PLA/ABS material,you need to try to make the part as smooth as possible.Some M2X6 （4pcs） and glue are needed to assemble the parts.
Before using glue between parts "bottom drive-UP" and "bottom drive-DOWN", you should try to test if the mechanism work well.

When you drive the part "bottom drive",the 4 blades open or close gradually. When it is open,the "mouth" diameter is 25mm.
STL and STEP format files are included.
