Pen y Fan and Corn Du circular walk
- Paths from
- Storey Arms and Pont ar Daf, on the A470
- Summits
- Pen y Fan and Corn Du
- On the print
- 6.9 km, as mapped in OpenStreetMap
886 m of mountain, 26 mm on your shelf
The print covers 8.3 by 8.3 km. On a 160 mm print the summit stands 26 mm above the valleys.
- Taller than life
The print opens with the Elevation multiplier at 2, so the mountain stands 2 times its true height and its shape reads clearly at this size. Set it to 1 for true scale.
- The trail
The Pen y Fan and Corn Du circular walk prints as a raised 1.2 mm orange line, drawn from its OpenStreetMap route. Give it its own filament color, or turn it off on the GPX tab.
- Colors
Forest, meadow, bare rock, ice and water each get their own color where the land has them, so a multi-color printer shows where the trees give way to rock.
About Pen y Fan
Pen y Fan is the highest peak in South Wales, at 886 metres (2,907 ft), in Brecon Beacons National Park. Its twin summits with Corn Du were once called Cadair Arthur, Arthur's Seat.
The National Trust owns the mountain and repairs its paths, worn by hundreds of thousands of walkers a year. The print raises it twice its true height to bring out the escarpment.
The Pen y Fan and Corn Du circular walk
Well-made paths climb from the Storey Arms and Pont ar Daf on the A470, 460 metres below the summit, over Corn Du to Pen y Fan.
The print draws a circular walk over both summits from OpenStreetMap.

How Pen y Fan measures up
Common questions
Is the Pen y Fan 3D print free?
Yes. The generator runs in your browser and exports a 3MF file you can open in any common slicer. There is no account or payment.
Is the Pen y Fan and Corn Du circular walk on the print?
Yes. Print this mountain adds it from its OpenStreetMap route (6.9 km as mapped) and raises it on the terrain. The footprint is 8.3 by 8.3 km, centered on the summit and wide enough for all of it.
Is the mountain printed at its true height?
It starts at 2 times its true height, about 26 mm of relief on a 160 mm print, because true scale looks flat at this size. Set the Elevation multiplier to 1 for true scale, or higher for a more dramatic model.
Can I get an STL instead of a 3MF?
The generator exports 3MF, which keeps each color as its own part. Any slicer can open it and save an STL if you need one.
