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.
