I'm over the moon with how the item turned out and even happier with how it was received.
She liked it, which was nice, and what she said about it was in line with everything i like about all my work. This matches her personality more than most things i make, but what she said about it was ...i'm repeating myself. It's nice.
The chain mated to the head via a slit along one of the wobble-equatorial edges. I'm sure a geometer would call that like the wobble-equator of an icosahedron, right? And then, natch', i potted it pretty thoroughly to the inside of the head with hot glue. This was after attaching the rest of the faces and getting everything square, dropping glue into a black hole so no pics. I was worried there'd be overlap or twist outside of tolerances to the final edges but it looks perfect.
I was worried the head would feel flimsy if the faces weren't better mated to the corrugated base, they're held on by hot glue, but sealing along the edges seems to've worked. There's just a little flexion and you've gotta lean on it. It's very precise but definitely handmade, which i should have on my business cards.
She commented on the flexibility of the chain, that was one of the 1st things she said about it. She opened it on stream ((https://www.twitch.tv/glorgana, give her a look)) and got comments about it being breakable but quashed them. She confirmed my observation that it's v. gratifying to sling over one's shoulder.
She mentioned how pleasingly detailed it is. Ones eyes can rest on it easily. If one has busy eyes, like mine and hers, there's endless detail to fall onto. Something something zen garden marie kondo. A thing of beauty is a joy forever (until it's not, cardboard falling apart faster (but no more than) iron and copper, lead and tin, glass and urethane...)
