While there are several wall mounts for Shark stick vacuums, the Rocket Pro doesn't appear to be one of them. This vacuum has a thin hook behind the canister which is clearly meant as a mounting point and so from this I reverse-engineered the wall-mounted component it inserts to. 

I also incorporated some tool holders created by Spongecretin found here: https://www.thingiverse.com/thing:4503870

The four screws seem to secure the hole thing solidly to the wall. I was concerned about the relatively thin wall being able to hold the full weight of the vacuum but it seems to to just fine.
