HVAC Locking Cap Tool

THIS IS A PROTOTYPE SO PLEASE GIVE ME FEEDBACK Had a coworker bring me a JB Industries Locking Cap Tool that had broken, it is obviously a common issue.He asked to make just a container for the keys but I took it one step further and modified a container to use the original parts from the JB Industries tool so he can still use it and store the keys. Printed in PETG, I stood on it's side (I'm 210lbs) with no issue, so it shouldn't crack with hand use.I added the magnet as an after thought and will probably recess the magnet after my coworker gives me feedback.The tool shaft and allen screw are recessed.
