A quick guide to keeping your file edits yours when you use a print service

I've had an issue where a vendor, one who specializes in resin prints, kept trying to upsell me on a digital license after I handed over the files for a small run of skirmish units. I was printing on a standard 4k resin like the Dragon or Lychee, and everything was fine until the final invoice came through. They wanted an extra fee just to 'retain the print,' which I felt was completely unnecessary since my copy of the STL was already archived on my own NAS drive. It was frustrating because I realized they weren't trying to steal the file, but they were treating the file itself as a revenue stream they wanted to control, even after the service was rendered. I firmly declined the add-on. I learned that for small-time hobbyists, the 'personal use only' clause needs to be more than just a polite request; it needs to be a contractual boundary. I started using a print management software to track those file licenses against the print order ID, which has prevented similar discussions about 'ownership' from ever happening again. It's just a bit of paperwork, but it saves you that awkward conversation at the counter. I also found that when I do need a vendor to keep a master copy for their records, I specify a destruction date of thirty days. Most shops are fine with that, but it sets a clear expectation that the file isn't sitting on their server indefinitely for them to decide to print again down the road.

That con situation is exactly why I stopped letting shops keep anything on file. Ran a demo table at my local show for the last nine years and twice now I've spotted minis on a vendor's shelf that I recognized from orders I placed, same sculpts, same base sizes, and one had my exact 28mm scale conversion on the pose. I asked about it and got a shrug and some story about 'similar files'. Since then I hand over a USB stick with a read-only copy and ask for it back same day, or I watch them slice it while I stand there. Slower, but nothing floats around after pickup.

That con story hits close. I found two of my sculpts at a swap meet table a couple years back, and the only reason I could prove it was mine was a tiny maker's mark I'd sunk into the base before sending anything out. It's a habit from my commissioned work, a shallow recess nobody notices unless they're looking. When I showed the vendor, the conversation went very differently than the 'similar files' excuse would have. Now every file I send out for printing has one, plus a slightly off-scale version I keep just for shops, so anything printed from it is a quarter size too small on the base rim.
