You can use AI now to design the STL files for printing.

This business ran from summer '24 to late winter '25. I looked at the time for AI generation tools, but things were pretty hacky then, and the general card stand shape had a lot of features built into it for better printing and assembly. I spent an weekend trying to do 2d to 3d on a pic of my Greyhound, and never got a 3d image that didn't have a glaring problem with it.

The one real optimization here, would be a tool that converts a logo into a multi-color print. There are some solutions like HugeForge that use height maps, or hacks you can do with an svg to convert it to an STL (shape) file, but I never found one that works. As with all this generation stuff, the killer is really the details: if things don't look good and you don't have an easy way to edit it, it's never going to work for the customer. Tracing is also just one step in the process, you still have to position it on the card stand and set up the multi-color print. That said, for complex logos, SVG -> STL might make sense.

I'm convinced I could vibe code something over the weekend that takes a logo, maps it to a set of colors using some sort of segmentation, then export that as a series of STL files that can be imported into Bambu Studio (or orca slicer) and then mapped on to a card stand.

If someone is looking for a project, an end to end "make a coffee table coaster from an image" would be a great web tool (or even CLI). Especially if you could enter the number of colors (or colors you have), modify the generated traces, and and export as a single 3MF file you can import into your slicer. That's complicated, but probably do-able in a few days.
