Metalfolding

Yep they're great have built about 5 or 6 of these now, tricky but great fun ^__^

these are nicer ones though... https://www.aliexpress.com/item/3D-puzzle-for-adult-2015-New-Star-Wars-3D-Nano-metal-Puzzle-DIY-juguetes-educativos-brinquedos/32377138812.html?spm=2114.12010108.1000023.1.SQBqxH

There are so,e pretty awesome ones out there, I've got 5 just in aircraft and a few others.

Only problem is that you need to go super slow and super carefully or else the entire thing is ruined with one bent piece.

Don't bother with buying the special kit, you don't need the clippers, they just ruin the pieces, it's easier to just tease the pieces off the sheer.
I've found that forceps and tweezers are the best tools to use, I also wear gloves to avoid getting them full of fingerprints.

I despise aliexpress because they stole free paper models from Canon and a couple others and sold them as pay kits.
But I do like Metal Earth. I've built many of their models, including the USS Arizona and a B-17 most recently. I've also built things ranging from a tarantula to the LEM to a Star Destroyer.
They require quite a fair bit of skill, but the results are rather nice.

yeah, i've bought star destroyer there, you get quite a detailed result for such size and prize
