@ddipaola I don't have a #G601 as reference, so I'm guessing into the blue. How many walls did you use for the print?
I'd consider PETG better suited for its impact resistance than the rather brittle PLA.
The LunchBox a a quite wobbly front bathtub as you know. Give I've replace the front “dampers” with dampers, I was able to mount a dome-cross-brace which significantly helps to strengthen that part by distributing impact forces. (3mm threaded rod and balljoints.)
Might that help here as well?
