The McDonald's Style McRib Pattie/Patty Press :)

You can print them in ABS or PLA (or whatever is your favourite).
Don't panic! The printed part will not come into contact with your food ;)

Just print the mold once and 2 of the inlays. Then print 1 handle and 1 pin. Push the pin into one of the inlays and press the handle (bottom covered in superglue) onto the inlay.

Put the other inlay into the mold (ribs facing up). Done.

Now just use wrapping film on the mold, put your minced pork into the mold, cover with another wrapping film and press with the handle inlay part your pork. Done!!!

Now you've got your McRib patty. Freeze them for 2-3 hours until they're solid. Now you can cook them in a pan for 2-3 minutes each side.
