molecule necklace pendants

Just a quick disclaimer, I did not come up with this idea.
There are loads of these molecule necklace pendants for sale on the internet
I just wanted to create a simple 3D printable one. (in this case 3 different pieces)

You can put them together on 1 necklace or just use them separably
whatever you prefer ofcourse ;)

I will post a photo of the ones i printed later :)
