Matterhorn, one of the most spectacular mountain in the world. Build its model in your sandbox. Whether just for fun and play or for educational reasons. Learning about geography will be more fun for children.
You can also talk to the children about what a valley, a saddle, a ridge, a pass is. Explain what contour lines mean. How water erosion works, why the Alps are sharper than rounded Krkonoše. And surely geography teachers will find a whole host of other learning activities with this tool.
Inner surfaces correspond to the exact elevation profile of the Matterhorn, obtained from touchterrain.geol.iastate.edu. The outer surfaces have all sharp edges rounded for the safety of children.
I recommend printing upside down. Firstly for easier removal of supports and secondly to more faithfully preserve the internal shape.
I am attaching the standard size model and the largest possible size model for MK3*.
*If I won the sand mold contest, I would print and photograph the large version as well.
The author marked this model as their own original creation.
