STLmint turns "can you make one with my kid's name?" into a print-ready file in minutes. It is built for people who sell personalised 3D prints through Instagram and WhatsApp orders, Etsy, craft fairs, and bulk requests from schools and offices, and who own a printer but are not CAD users.
A seller picks a design, types the customer's text, and sends the customer a server-rendered picture to approve. The picture is rendered from the exact file the seller then downloads, as a full-quality STL or a two-colour Bambu Studio 3MF, so there are no misspelled reprints.
Highlights:
- 725 designs in 21 categories. Keychains, bag tags, pencil and cake toppers, signs, NFC business cards, pet ID tags, home gifts, desk accessories, garden markers, seasonal keepsakes, and more.
- Bulk orders. Paste a list of names and get a ZIP with one STL per line.
- Templates that handle the design work. Lettering, spacing, and fit are worked out by parametric OpenSCAD templates, rendered on the server with OpenSCAD compiled to WebAssembly. The template sources never leave the server.
- Print-aware details. Two-colour 3MF output, NFC card pockets with an automatic print pause, and a shared wall-mount standard so signs and plaques swap on one bar.
- Passes and a Seller plan. Party and Season passes for one-off events, and a Seller plan with commercial use and higher limits for people who sell every day.
