This is a 25mm ID EDF case designed to hold an 8.5mm diameter motor. There are no mounting holes on this as it is assumed the motor used will be a brushed motor. It has an end stop at the front of the motor housing.
The thickness of all sections is ~0.8mm to provide the lightest possible solution while still maintaining a minimum amount of structural strength.
