Flat Cut Tool

(R=0.7mm to 2.6mm) / (2R=1.4mm to 5.2mm) [1.4_1.6_1.8... etc] No support need while printing. It needs %100 infill, otherwise you will cut the shell on the first knife move! I suggest use 0.4 nozzle and 0.1 layer or under. Good things require patience ;) Note: obj file is like stl. You can easily use it in the slicer program. Needs m3x10 bolt X3 m3 nut X3
