The model of the Grand Canyon was created using TouchTerrain (https://touchterrain.geol.iastate.edu/). I created the frame that it goes into, however you do not have to use it. It is a fairly thick model already so it can be hung on a wall or displayed somewhere just as well by itself. The only reason I created the frame was because the edges of the model are all different heights so I wanted to hide it by putting it into a frame.
Printed using default settings in OrcaSlicer but feel free to mess around with the settings and see how it turns out. I do not recommend scaling up as you will more than likely lose some quality.
I hope you guys like this as it is the first model I am uploading and plan on creating more of different landscapes.
The author marked this model as their own original creation.
