Heartbeat. Children's jewelry with holographic animation

This is a simple children's ring, medallions and a pendant in the form of hearts with holographic animation (yes, my daughter loved it!).
The video shows how hearts "pound":

I decided to use the holographic principle that I showed in previous projects:

In addition to the ring with one beating heart, I made medallions with two, four (they resemble clover), and a polyhedron pendant with eight hearts. These are "pendants of friendship", children can consolidate their acquaintance.
All models you can modify as you want or sell without restrictions.

UPD
I added a piece of holographic hearts ornament that can be scaled up to infinite size. Use it without limits in your projects!

Print instructions

Usually I do projects that do not need support, but here supports are appropriate for the ring and medallions (for a locket with 2 hearts, I did forced supports on the first 15 layers). The polyhedron pendant must be printed without supports.
It is worth giving a brim (I set a small 3 mm), except for the ring and pendant.

For printing, you should choose the most shiny plastic, for example, the one called Silk. However, it even works on regular black PLA or PETG, if you slow down the speed a little or increase the temperature. I think dark shiny materials have a slightly stronger effect than lighter ones.
Layer thickness 0.2 mm, width 0.45 (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, 20-40 mm / s, turn on the cooling.
The slicer can have some "errors" in the model - this does not affect the result in any way. In addition, PrusaSlicer fixes them automatically.

All models can be slightly reduced or enlarged.
