So, you have bought a tool kit and the case turned out to be the best part of it, did ya!
Well I did anyways! So here is the modification to make the tool case much better for storage use to keep critters out and food safe.
step 1. get rid of useless tools
step 2. Sigh and re-purpose case
step 3. how you do it. Open Case determine how the pressed inside form fitted is attached to the case on the base.
step 4. find a line and cut around using a Die Grinder, it is like a Dremel tool only powered by air not electricity.
step 5. remove the inside liner, clean it and you have a much more user-friendly case.
I left the top part as it is plastic welded in as well as only gaining 1/2 of an inch, so not worth the time. Later I may change my mind anything is possible.
