Hello, So I am doing a project for college that uses gazebo, and I have been meaning to add a model into gazebo, but is a really simple model, its just a bunch of disks of different diameters stacked together on top of another, starting at the bottom with the largest diameter.

I searched videos about adding models, but they seem to be all about assemblies, and needing to use blender as intermediary and for me its seems kinda complicated. Before I invest the time learning, is there a simpler way to add this model of mine I made in SolidWorks? It's a part, but I can make it a assembly too.
