Gourmet Hamburger Press

It's official, a gourmet burger is 4-1/2" (115mm) in diameter and has an indention in the middle of both sides to compensate for middle swell while cooking.

Of all the presses I found, none met this criteria. So here it is! Simply print the housing and two inserts. No handle needed, easy storage.

Enjoy the gourmet sized burger!

6-22-15: Added version 2 of the insert which is a little wider and the bevel slope less steep. Meat displacement is about the same, just a smoother patte
