Own product: Personalised poster studio and store
Heartysan
Customers design sound-wave, star-map, city-map and moon posters in the browser; the studio exports print-ready files.

The task
Our workshop sells personalised posters printed on paper and brushed metal, some with 3D-printed parts. Every order needed manual design work in several desktop programs. We wanted customers to design the poster themselves and the workshop to receive a file that goes straight to print.
What we built
- Generators for sound waves, star maps, city maps, moon phases, lyrics spirals and mountain maps, all with millimetre-accurate geometry.
- Poster editor with layers, snapping, grouping and per-material preview on paper, frames and four metal finishes.
- 3D export: two-colour 3MF for Bambu Studio and GLB for rendering, plus a city-relief printer.
- Store with accounts and checkout; listings are published from ShopFlow and mirror the Etsy offer.
