Thanks for your comments Larry.
We will take a look to that issues with the Simplify3d.
On the B-robots project´s page the manufacturer´s motor model is indicated as 42BYGHW609. That is the motor we used to create the 3D model (with its dimensions).
There is a more complete B-robot electronic KIT with the battery holder/motors/strap/bolts/power switch and custom cables (http://goo.gl/OexVBH).
Could you email us with your motor manufacturer´s reference so we can have a look to its dimensions?
