For a (50 or less) x 22 x 12mm eraser, use the provided .gcode file with an Ultimaker 2 printer. If your eraser size differs, modify the dimensions in the .sldprt file using SolidWorks. The G-code is set to high quality, producing 2mm thick walls for a sturdy case that feels premium. Note that initial insertion of the eraser may be challenging due to inner lines, but grooves will form over time. Experiment with dimensions if you wish to adjust line aggressiveness.
