Cordless drill dimensions

[Coolspeedbot]

I have been looking around but I haven't been able to find the dimensions of Cordless drill motors and their gearboxes and I was wondering if anyone could tell me what they are so I can plan how big my feather weight will be.

There are a few generic brands, reasonably cheap and ready for disambling.

And here you have an example of a custom version.

I already have a pair of 12 volt drill motors in mind I just want to know the approx. size to plan out how big the mounts need to be and how wide the robot needs to be to fit them.
