Set of earrings with holographic animation

Photos do not convey the effect of holographic 3D printing much, watch it in the video:

This time I decided to work not with the form or structure, but with the surface. It was important for me to find out how light is reflected and control its movement. To do this, I formed a surface from small pixels. Each flake is located at a special angle to the surface plane. Their groups make it possible to see several phases of light reflection. In the last project I started experimenting, now I managed to achieve the movement of various geometric shapes: a square, a circle, lines, a star, a zigzag. I named the series after my favorite artist and master of optical illusions Victor Vasareli.

UPD
Check out my new project where I added a piece of holographic heart ornament that can be duplicated up to infinite size. Use it without limits in your projects!

Print instructions

For printing, you should choose the most shiny plastic, for example, the one called Silk. It even works on regular black PLA or PETG, though. I think dark shiny plastic have a slightly stronger effect than lighter ones.
All files are printed without support, but it is worth giving a small brim (I set 3mm). Layer thickness 0.2 mm, width 0.45, nozzle 0.4 (I think it is possible to make a smaller layer thickness and height, but I have not tested this). The parts are small, so it is better to choose a small speed, for example, 40mm / s and turn on the cooling.
Slicer can detect some "errors" in the model - this does not affect the result in any way. In addition, PrusaSlicer fixes them automatically.
