Build a printable model of central Durham from OpenStreetMap footprints and LiDAR heights. Give every building a roof height, or shape the roofs from the surface model, remove detail too thin to print, and prove the city and its two-colour parts are watertight.
Split a 3D-printed model of Yr Wyddfa (Snowdon) into four watertight colour parts (water, woodland, open ground and high ground) from Copernicus GLO-30 and ESA WorldCover, remove specks too small to print, and write STLs and a 3MF for a Bambu Lab AMS or Prusa MMU.
Turn a GPX track into a printable terrain model: the Pennine Way from Edale to Crowden, draped on Environment Agency LiDAR, with the route raised, engraved, or printed as a separate colour inlay. Every STL is proved watertight before it is written.
