Helical gear for Vidateco shredder

Replacement helical gear for cross cut paper shredder Vidateco OS-060C.
Helical gear has 37 teeth with 28 degrees helix angle, 20 degrees pressure angle and 0.785mm module, normal system.
Spur gear has 7 teeth, 30 degrees pressure angle and 1.61mm module.
In order to not being forced to print it with supports, I created a suitable size washer to insert first, and then the gear, to keep the correct distance.
