Townsmith
Designs 3D-printable modular tabletop terrain in your browser, exports STL files.
Townsmith is a browser-based toolkit for designing 3D-printable tabletop terrain: Townbuilder for fantasy towns, dungeons, and interiors, and Battlefield Builder for wargaming tables. Both export support-free STL files sized for personal printing, and the site also sells themed asset packs across 16-plus themes plus a library of ready-made building layouts. Merchant licenses are available separately if you want to sell prints or digital files commercially rather than just print for your own table.

What holds up
- +Exports support-free STL files — no post-processing to strip supports before printing
- +Two dedicated builders — Townbuilder for interiors and dungeons, Battlefield Builder for wargaming
- +Supports multi-color printing workflows, not just single-material output
Mind the limits
- −Commercial print-and-sell or digital distribution needs a separate merchant license
- −Design tool runs in-browser on Townsmith's site, so building layouts needs an internet connection
