Design a 3D printable ceramic cutter with the exact shape of the provided image. The cutter should be optimized for printing without supports, featuring a clean, sharp cutting edge and a comfortable handle or grip suitable for ceramic work. The design should be solid and robust enough for repeated use, with a uniform wall thickness that allows for easy removal from a 3D printer bed without breakage. Focus on smooth contours and a structure that minimizes overhangs.
