I cut my "motor box" from 1" 6063 aluminum square tubing.
 
It's not too heavy, weighing in at 5.5 grams.
 
As a comparison, the forged brass motor bracket I purchased weighs in at 8.4 grams.
 
   
 
I then fabricated the motor box supports which connect it and keep in located onto the chassis.
 
   
 
Here is the motor box and the supports prior to assembly.
 
   
 
Thanks.
