Another example why I love 3D printing.
First gear. For the monet is fine. I will print other at higher temperature to see if changes something. This one is at 260C (post processing boiled 30 minute and cool down in water), that is the max temp suggested, but I read of people printing at 275-280C. I will see 
If it doesn’t work then I will try stronger material and otherwise I will machine it spur gear. This one is helical so need a 4th axis to machine it.
