The file 'Keep Calm Ambigram 3D Printer Model' is (stl,gcode) file type, size is 1.1MB.
This is a 3D ambigram that I made in TinkerCAD. You can see this in both front and back with one side saying "KEEP" and the other one saying "CALM". Supports are really important because otherwise you will only get the base with half formed letters and noodles on the side ;).
