Make temporary cardboard one while you think of a better design to make in metal. In three years reinforce the duct tape holding it together. In 10 years think about the metal one again but make a new cardboard one which somehow won't be as good a fit as the trusty old one……………….etc.
Cardboard Bazyle – are you living in the Stone Age? 
What you need is a piece cut out of a plastic liquids container, such as vinegar, screenwash, etc, 2Litre, 2.5Litre, even 5Litre depending on size required. Provides top, 2 sides, and end all in one. Simply clamped between motor base and mounting plate.
I had one like this until one day decided on something smarter in metal. So cut, soldered, riveted, painted, fitted it; and the damn thing rattled and vibrated fit to bust. back to the plastic.
