Ryobi 18v x3 Battery Holder for Wall Control Pegboard

Mount 3 Ryobi 18v batteries to wall control pegboard using the DDD Printable Wall Control System. 
 

Note: If you use the center piece to combine two of these together, the middle batteries will be rubbing together a bit. They fit, but it is close.

Another great model in the photos:

Hack and slash is how I model. Cut the wall mount off and used the parametrized DDD centerpiece template to affix the important bits. 

I only modeled the 3 battery version, sorry it is all I needed.
