Topographic map - Bern, Switzerland

!! Print at 3x scale, else tolerance will be incorrect !!

The following datasets were used:

• height model: swissALTI3D
• landscape model (Buildings): swissBUILDINGS3D 2.0

Steps:

1. Combining the height model and the landscape model into a single large 3d Model with QGIS and some postprocessing with AccuTrans 3d.
2. Cutting the file to a region of interest with Superslicer
3. Generating the puzzle stencil with OpenSCAD and a script from a prusa3d blog post.
4. Using blender to cut the model with the puzzle stencil
5. Separating parts into individual files with Superslicer
6. Slicing for 3d printing with PrusaSlicer 2.5.0-alpha3
   • Using the new Arachne engine to improve printability of small houses
   • Using the new lightning infill (10%)
   • printed at 3x scale on a modified Ender3Pro → approx 1:7'000
7. Glued onto an MDF board with epoxy
8. Mounted to the wall using Wall Fixing designed by ZacSimmo
