No. What I’m saying is the tooth profile is not the correct profile for a GT2-3mm pulley. It may work with the loose tolerances of a 3d printer, but it is not correct. The profile in your file has only one arc plus the fillets at the top of the teeth. The actual profile should have several different arcs. The depth of the valley is also over .1 mm too shallow.
The purple line is the profile from your file, the light blue profile was created in Gearotic. The Gearotic profile is correct, but is made up of many short line segments, so it can take a long time to mill.
