- Inland Red PETG which actually turns out magenta which is why I am using it up making cookie cutters :)
This was originally done as a joke, but it seems they have become quite popular amongst friends and family so I thought I would share.
The file makes a cookie about 8 inches (200 mm) long by about 2-2.5 inches wide. It is for cutting dough that is rolled to a maximum thickness of 1/4 inch (6.35mm). Brown food coloring was added to the dough to give it a "natural-ish" look.
To start, I created a drawing in Inkscape:
I exported it as an .svg and opened it in Fusion 360. I drew another outer perimeter to make the cutting wall. Then I extruded various parts to different heights do put detail into the cookie dough so frosting the eyes and other details would be easier. Here are his dimensions.
I printed it out lying top down with what was supposed to be red inland PETG, but prints as a magenta color. I used 50% infill and some of the other settings are visible below. I get good results at 245 degrees C for printing PETG on a 60 degree bed.
Here is the finished product:
And the delicious products born of Mr. Hankey's Christmas spirit.
