Low Boy Utility Case - Full Width Inserts

I love the utility case, and have several circumstances where a liner is a practical addition (different print material, etc), but without all of the subdivisions.  

I think there are other models on printables that are the same as this exact one, but I found it hard to find them.  

This is for anyone who wants a full width liner but isn't interested in modifying the original STEP file (found as a file in the original model) to make their own variant.

Original model included a STEP file for the tray inserts / liners.  This is a tray liner adaptation to fit within the original model. Useful for those looking for the same thing, but don't want to make the modifications themselves.
