Thanks! And yes, cooling holes will be needed. I am thinking 15/64" diameter, eight places on a 0.931 circle. Or something like that.
These motors do need air flow-through, or they'll cook.
Also, the detailed dimensions visible on the drawing may not be correct -- they are based on 0.8 module gear teeth -- actual tooth size is more likely 32 DP. Also, they are based on a 19 tooth pinion, and our -9013 motors have 13 tooth pinions.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
