Plastic Recycling Symbols STL/FreeCad

I really enjoy 3D printing and I use it to make all sorts of things. But there is one thing that we do have to realize: whatever you may print, it will not last forever and there is going to be a day that you (or someone else) would have to dispose of it in a correct way.

By recycling plastics we can save energy and keep the earth clean so that we do not contribute to the plastic soup and microplastics in nature.

While more and more materials become available for 3D printing, would someone still be able to recognize which of them was used years later?
Most of you may print in PLA, but even PLA will not disintegrate in nature like conditions.

The good news is that people once decided to create unique symbols to identify plastics all around the world.

So here is my take on the recycling symbols free to use in your projects in STL and FreeCad formats. For now I have 7 materials that I believe are most used.
More are on the way. If you miss a material, just leave a comment.
Please like this thing to draw the attention that it deserves.
