Let's be honest, we geeks have been doing this whole 'diversity' thing for decades. And it's been REAL diversity, not the fake kind shoved in our faces by the PC brigade. The symbol of this is the IDIC, symbolising Infinite Diversity in Infinite Combinations, the cornerstone of Vulcan philosophy.
This pendant isn't completely 3D printed; you'll need to find a stick on jewel to make it complete, but you can get sheets of hundreds from your local art supplier. But aside from that you should be able to slap it together pretty easily.
This pendant is available, printed and assembled and with a range of coloured neck-cords, in my Etsy store - www.etsy.com/uk/shop/enterprisexddesign
