Metal can / box inserts

I have seen many inserts for Altoids tins. Unfortunately, these are not available in Germany (at least I haven't been able to find them anywhere yet) and these inserts don't fit in my tins because the metal wall protrudes slightly into the tin. That's why I created inserts for standard metal boxes, which can be purchased on Amazon or Ali Express. Here are the dimensions:Standard metal boxe measuring 98 × 63 × 21.5 mm. Dimensions of the inserts: 89.5 × 55 × 21 mm.Printable in any common filament (PLA, PETG, etc.).No supports needed.
