I haven't seen a wall mount for the Milwaukee Blower 3017-20 (newere 500 cfm version).
It uses a dovetail sort of wedge shape, screw this mount to the wall and the blower will slide right into it.

The holes I have are for 5/16" bit tip screws (#10), I have uploaded other files with the design in them if you need to make any modifications.
I'm not a professional designer, use at your own risk, but it works!

Let me know if there's anything you'd like to see changed and I'll try to work something out… enjoy!
