VERSION 2 [BETTER]
This version I extended 2 of the micro sd slots to work with full size SD cards and converted the small wrench slots different and cut open all the way through the nozzle holes as I could knock them off too easy with the original design….I also trimmed 1mm off each side just to make it a little less material.
