This is a replacement latch for our workplace toolboxes which had broken. Fits Trifibre Challenger and US Pro cases/toolboxes. I have printed them in PLA but if they dont work out then I'll try PETG.

UPDATE: after “rigorous” real world testing, I've found that ABS with 7 perimeters works best. I've tried a few versions with PLA and PETG but the 7 perimeter ABS version is surviving all the beatings
