Hanging storage system for hot wheels monster trucks, the hangers mount using Medium (listed as 2.8") 3M command strips and the jig has a built in spirit level holder that takes a 9.5x40mm spirit bubble. The jig will space out vertical and horizontal spacing as well as do a slanted pattern if you offset one of the hangers.
I recommend printing the hanger on its side (so its tall as it can be), you will need supports on the upper wheel area.
The jig should not need support at all, but i did print it at .20 layer height to avoid any overhang weirdness
