Lid for Canned Dog Food

This lid is for a can with a lid diameter of 75mm (as measured on the outside of the top metal seal ring). The lid consists of two parts:

• Ring - this has a loose press fit onto the can top

• Lid - this cover is a snap fit into the ring

I made this in two parts to that I could add a design to the top of the lid, and print the design in a contrasting color using filament switching. I also included a lid version with no design in case anyone wants a plain lid.

It should be noted that 3D printed items are not considered food safe unless they are coated with a food-safe impermeable coating.

Print Instructions

Print in PETG on a textured sheet using the 3mf or gcode files provided. I used PETG rather than PLA so that the lid can be washed in hot water (even though in normal use it does not contact the can contents). In general :

• 0% infill

• 3 perimeters

Print the ring top down for best adhesion.
