A 3D metal puzzle is a model kit cut from stainless steel sheets. Most snap or screw together without glue. The things to check are part count, the build time the maker gives, whether tools come in the box and how large the finished model is.
The six kits below cover a pirate ship, a bumblebee, a leopard, a dragon, a scorpion and a manta ray. Details come from each listing page and are the makers’ own. We have not built these kits ourselves. Where a listing disagrees with itself, we say so.
