Quest 2 controller 3d models? (Not the ones in .fbx)

I am a user who wants to make 3d printed Beat Saber handle. But I can never get Quest 2 controller's 3d model. The ones provided in Controller art, is weird. They stuck two controllers (L/R) and I can never separate them. People says I need Fusion 360 to open and separate .fbx files, but I don't want to spend that much money just to open .fbx file and separate them. (What the heck, the free personal Fusion 360 does not support .fbx files.) Any ideas?
