In searching for sites that contained a large number of STL files, I stumbled across GrabCAD. This site contains over 80,000 STL files. (Most of the files on this site are engineering based, but there exists a handful of mathematical objects such as knots, fractals, and klein bottles). It also has a program that may come in useful at some point called GrabCAD. GrabCAD theoretically is beneficial for getting external input on your 3D model. However, upon further inspection, it may be no more effective than plugging a 3D file into a shared Google Drive folder.
All the same, go check it out! You might find something awesome.
