Ok, I have no if it’s the first, but it’s a good click-baity title. I made a Rhombic Triacontahedron a while back as part of a workshop I hosted showing how I create my polyhedral connectors:
But I never did anything fun with that shape. I bought some scrap leather off etsy a long time ago, and thought I’d skin it with an engraved leather.
That one looks almost medieval! Very nice! 
Fantastic!
What fun geometry. 
Very cool!
This is so awesome!! Love the engraving!
I love it! The leather is a great idea. @Jules is right, it looks very medieval. Soccer matches in full armor should be a thing.
That is flat out gorgeous!
It’s gorgeous!!!
Beautiful work on this one!
Kind of breaks my brain! Nice work.
What a cool combination of ultra modern and Old Worldly feel!
Wow. That is beautiful.
Thanks for posting the video Mike, I found it really interesting and learned a lot. Just a quick question about how you fix the connectors. Did you thread the holes in the connector, or put nuts on the inside? The potential problem I see with using nuts is they won’t tighten down flat against the inner surface. Or did you use threaded inserts?
I use 3d Printed connectors, and design them so the screws just self tap in to the plastic. No nuts required.
So do you like have 1000+ of these around the house? Too COOL!
Thousands? No. But too many.
This is outstanding, have you thought about entering it into art shows as mixed media art? I have found some success in doing that with acrylic pieces held together with nut and bolts with straps made from veneer.

I used to do juried art shows with my photography, so I’m aware of the potential. I’ve thought about it and remembered how much work it was!
