I’ve wanted to make a 3D model of your robot, but the program I am currently using does not support the assets the models for each part comes in (.STEP). Is there a way I can simply convert to .stl without an external program or find a separate .stl list?
If you are serious about 3d modeling, I suggest you take advantage of the free software available to robotics teams: SolidWorks, Fusion, or Inventor. The attached white paper may be helpful.
I don’t think you’ll find .stl files of every robot part as these are not parametric CAD models, they are mainly used for 3d printing of parts.

As stated by @kmmohn,
files are meshes, not parametric CAD models. The
file format, as a result, loses information compared to its parametric counterparts.
Solidworks, Autodesk Fusion 360, and Autodesk Inventor are indeed free-for-education, industry-standard parametric CAD tools.
FreeCAD is another great tool that also supports the necessary features for VEX. It is completely free and tends to be a bit easier on system resources.
