The three year old girl across the street was having her birthday and wanted it to be a Princess Teapot Party. My wife used Casement's nice cookie cutter to make some cookies and wanted to make some sandwiches as well but wanted the edges a little sharper to cut through the sandwich better. I had never remixed anything before but I took original, ran it through tinkercad to convert it to an SVG, imported it into Inkscape and did some mods. I then ran it back through tinkercad to create the STL. I'm not the best at this kind of stuff and would like to have constructive criticism if possible.
It is hard to see in the picture but the original (pink) wall thickness was 1.75mm on a 100mm wide cutter. The remix (blue) has 1mm walls on a 110mm wide cutter.
My wife says that bread that is FIRM is easier to cut. She made both PB&J and Ham/Chess sandwiches after cutting cookies with it.
