The file 'BBS Mesh Wheel 3D Printer Model' is (stl,stp) file type, size is 28.1MB.
This is NOT my design. Downloaded the STEP file from GrabCAD here:
https://grabcad.com/library/wheel-15x7-1
From there I simply converted the STEP file to STL and printed it. Used supports and printed the wheel face-up as you'd expect. Printed actually REALLY nicely for my machine. This was in moderate quality, and I'm still very pleased with it.
