Nespresso cap designed as toy

I designed a nespresso cap so my son can play with the coffee machine without using real capsules. He likes to make coffee for us and so we looked for a defect machine. To take out the pins which poke the holes in the cap is a lot of work, so I designed a cap where the pins will not poke holes into the printed part.
If you do a color change after 2 layers starting with silver it also looks quite like a real cap.

I printed it in PLA. So the print was quite easy to crack -> first 12 layers 100% infill den reduces to 25
