Wind Spinner (hiệu ứng quang học)

The shape consists of 10 individual squares (and a center one) increasing in size. After printing, the individual squares are provided with increasing angle bending by means of a mold. The mold can of course be used several times!

It is important that the squares reflects light well. It is best to use silk PLA/PETG or PLA/PETG with glitter. Afterwards spray painting with e.g. chrome, gold or glitter paint is also a good option.

For maximum effect I printed on a flat plate.

Print all with 0.4 nozzle and 0.2mm layerheight. For the squares I used concentric infill for both bottom and top to maximize reflection.

After printing clamp both halves of the mold over the center line and gently poor hot (boiled) water through the center hole. This will set the bending so it will be permanent.

Hang on a thin fishing line.

To keep it tensioned an extra weight kan be added at the bottom. Just fill the weight casing with some coins or washers for weight.

Recomendations for scaling:

* I Used 133,33% scaling for the ones on the photo/video.

** When hanging multiple under each other, let them spin the same direction. Otherwise they will work against each other and turn less with the wind. The bigger the square the heavier the weight should be.
