Enjoy it as a course for various mini crawlers.
The shape is different, but please refer to the reference video for production.

Based on the 3D data around Everest, I made a diorama that fits in the art frame with a 3D printer.
The mountain was transformed into a rock face, and the flat part was expressed as gravel.

I'm worried about the texture of the mountain part as it is output by a 3D printer, so I mixed water-based paint with baby powder whose main component is talc to make the surface matte and uneven.
The gravel part is strongly bonded by diluting the woodworking bond with water.

Rhinoceros + Grasshopper is used to model the 3D data around Everest in a rocky manner.

Originally, it was a prototype that I thought about when playing the R / C mini crawler in the room, as an art frame when not in use, and simply placing it when using it.
The height of the 3D data around Everest is optimized because
