DIY gourmet hamburger for your hungry tummy :-)

Recipe for 4 persons (I'm Italian, trust me)

• 500g minced meat
• 1 shredded carrot
• 8 green olives (in small pieces)
• ¼ onion (in small pieces)
• 5 tbsp breadcrumbs
• 2 tbsp mustard
• 1 egg
• salt
• pepper

Mix together with your hands, create 4 balls, put in the containing ring, press firmly, cook it in the barbecue or where you like. Enjoy :-)

NB: I used PETG and many perimeters for the sidebody (so as to have 100% infill)
