About this 3D model

Mintronics:Survival Pack tin top shows an insert but the tin did not contain it. So I tried to create with my 3d printer. Needed a little bit of shaving on the corners and on top, but otherwise does the job. Could possibly use for altoid tin as well :-) This object was made in Tinkercad. https://www.tinkercad.com/things/kXquz5vjc9a
