Terrain STL files of individual US states? (lemmy.world)

Does anyone know of a good resource to download or generate terrain / elevation STL models that are bound to the shape of US states?

I came across this posting but the files are pretty low resolution and look pretty bad at the size I want to print.

The cert has issues, but what about this: https://www.jthatch.com/Terrain2STL/

Check out Winston Moy's video on making a topographic map of Colorado. They mention these data sources:

OpenSCAD's surface primitive can turn height maps into STL files.

You may have to trim the state boundaries yourself. :(

Thanks! I've made lots of wide area and close-up terrain models using DEM and lidar before, but trimming to state boundaries has always been the challenge. Every time I try to trim the raster data in qgis I don't get anywhere, even though it should be possible.

The OpenSCAD primitive is a new one for me though - thanks! In the past I've just used the DEMto3D plugin in qgis.
