Simple model to print and put a lid on opened cans. Your printer needs to be calibrated pretty tight as this is measured exact and provides a good fit. May not work with bent or damaged cans.

Use PETG for the flexibility. Pretty standard settings:

• 60% infill for the finger grips (the only area that infills)
• 2 perimeters
• .2 layer height
• .4 Nozzle diameter
• No supports
