Mt. Everest - 3D text with topography

This is a small project I used to highlight a technique in PrusaSlicer for printing only the intersection of two objects. In this case, it is a text that shows the topography of Mt. Everest and the surrounding mountains on its top. The effect is visible mainly from the side.

You can read the step-by-step guide for this technique in my Printables article.

The original Mt. Everest terrain model was generated using www.map2stl.com

Printing instructions

Import the file into PrusaSlicer, and make sure not to change the Per-object settings in the right panel.  (I haven't tried with other slicers, but it might not work, because they interpret modifiers and settings differently). 

A detailed description is in the guide linked above, but basically the terrain is set to be printed with no perimeters and no infill, and the text modifier overrides the intersecting area to be printed normally.

Optionally, you can right-click the text and edit it (change the font, size, etc.). Note that this will probably reset its position, so you might need to move it back up. The font should be pretty thick to print well.  (The font I used is from Windows, so it might be lost when opening on a different operating system).

There are some overhangs on the letters (specifically, the "T"s), so printing with supports is recommended for a nice finish. Otherwise, simply slice and print with a 0.2mm layer height using PLA.
