Thank you very much!
quick search didn't show me DH Involute Gear,
however I just take faces and push them to desired thickness
It was obvious and I don't know why I didn't do this from the very beginning
Sorry I was stupid

Hello!
Could you please check this:
I need to 3D print so need mm instead of inches
Pitch is in mm, but Face is in inches; typing mm is not working because of floating value
I read that I can change this in .rb file,
And find out that SPGears do not exist neither in Manager or in Plugin folder..

Any options I can try?
Thank you!
