Your own models
The piece you already have,
as a model you can sell.
Photograph what is in the case. It gets rebuilt: read once, then made again by the same bench that builds everything else here, so what you get back weighs something, prices itself, and changes when you say what is wrong with it. Anything you have already uploaded is still below, and still opens.
…or drag them in. Up to 4 photographs of one piece.
