About 25 yrs ago I made a case for my Trend worktop jig, it looks like a wooden rifle case with a piano hinge and two briefcase type catches, it has kept that jig protected all this time through moves abroad, house moves and job sites/workshops.
Maybe making something like that would serve you well too.
I will get a pic of mine when back at work, away at the moment due to mother in law's death.
