For a left-hand version, mirror all the blades and the front/back covers.
Colors: The fan from the pictures was printed in 2 colors by adding a “Color Change” step. Height will depend on your layer height settings:
Front Cover & Blades 1-9→ ⬜🟥
Back Cover → 🟥⬜🟥
For better results, make sure the printing seams are not on the sliding surface of the pin (see picture below). You can use the “Seam Painting” function to block/enforce the seam location.
Assembly instructions (see picture)
Align all the blades, including the front and back covers.
Insert the hinge rod
Add the hinge caps
Enjoy! 🪭
Note: The fan will unfold more smoothly as you open and close it a few times.
