I made a program to turn my flights into 3d prints

A Reddit user in r/flying has released AeroMesh, an open-source tool that converts ForeFlight KML flight logs into 3D-printable models of a pilot's actual flight track. The program pulls real-world Digital Elevation Model (DEM) terrain data, layers in building footprints for urban context, calculates the aircraft's exact height above ground level (AGL) at each point along the route, and automatically generates support pylons so the printed flight path appears to float above a scaled replica of the terrain it traversed. Because the project is published on GitHub, any pilot with a ForeFlight subscription and a 3D printer—or access to a print-on-demand service—can generate a physical memento of a specific flight, whether that's a scenic mountain approach, a cross-country training flight, or a memorable check ride.

For working pilots, this kind of tool sits at the intersection of two trends that have quietly reshaped general aviation culture over the past decade: the ubiquity of high-fidelity EFB logging and the maturation of consumer-grade 3D printing. ForeFlight, Garmin Pilot, and similar apps have long captured detailed track logs with GPS-derived altitude, groundspeed, and position data, but that data has mostly lived in digital form—viewed once during a debrief or archived and forgotten. AeroMesh represents a small but telling example of pilots building grassroots software to extract tangible value from data that flight departments, training organizations, and individual aviators already generate as a byproduct of normal operations. It also reflects a broader maker-culture trend within aviation: pilots increasingly treat their own operational data as raw material for personal projects, from custom yoke mounts to panel-mounted flight tracking displays, rather than leaving all data science to avionics manufacturers.

The terrain-and-AGL calculation piece is worth noting from an airmanship standpoint as well. Accurately modeling AGL against real DEM terrain data requires solving some of the same geospatial problems that terrain awareness and warning systems (TAWS) and synthetic vision systems address in the cockpit—correlating GPS altitude against ground elevation at high resolution. While AeroMesh is a novelty/keepsake application rather than a safety tool, the underlying techniques (DEM sourcing, terrain meshing, AGL computation) are conceptually related to the datasets that power terrain databases in modern avionics suites. Pilots interested in the guts of how TAWS or synthetic vision terrain rendering works may find an open-source project like this a useful, low-stakes way to understand those computations firsthand.

More broadly, this kind of community-built utility underscores how open flight-data ecosystems and open APIs from EFB providers enable a long tail of niche software that neither ForeFlight nor hardware manufacturers would build themselves. Flight schools, aviation museums, and individual owners have already used flight-track data for things like personalized route posters and social-media flight-sharing tools; a 3D-printable terrain-and-track model is a natural extension of that trend into physical keepsakes. Operators and flight departments with training or marketing budgets might see appeal in commissioning similar renderings for milestone flights (first solos, check rides, retirement flights), and the open-source nature of the project means CFIs, DPEs, or aviation clubs could adapt or extend the code for their own use cases without licensing friction. As EFB data export standards remain open and well-documented, expect more of these small, community-driven tools to surface, further blurring the line between flight logging as a regulatory/operational necessity and flight logging as a source of personal aviation memorabilia.
