This model was created to maximize workbench space be creating a place for your tools when they are not being used. The holes on the back allow the model to be mounted to a wall via screws. and I added some bins to make a place for all those screws and other hardware that keep trying to find a place on your floor. 

The thingrail can be scaled up to  150% to provide room for bigger tools. 

Also you my want to do some light sanding on the rail itself because its a bit of i tight fit
