Plano Edge Jig Box Fix

There have been some folks (including myself) who have mentioned that some of their jigs will not fit snug in the Plano jig box.  Today I finally had the opportunity to test an idea and it worked great.  I used heat shrink tubing over the arms only for the smaller sized jigs and they all now have a snug fit.  I have included pics of the box as well as the tubing package (Home Depot electrical section).  Hope this helps.
