How can I make a STL of a topo map perfectly round?
With theis KML [circular generator](http://kml4earth.appspot.com/circlegen.html), and this [STL generator](https://touchterrain.geol.iastate.edu/) it is possible to create round 3D printed maps like this one.

However, the KML circle isn't perfectly round and that leeds to the bumps on the edges you can see.

Is there a program where I can trim the original STL so that the result is round instead of jagged?
