Moiré pattern extrusion visualizer

thingiverse

2-piece moiré pattern maker: the 2-color piece clips onto the extruder motor, and the screen (with a magnet) rotates with the motor shaft. To print with PrusaSlicer, import "Motor_cap" first, then import "Motor_cap_white_lines" as a child of it: it should line up. Then make that face down, and print with black for the clip and white for the lines with mmu or just manually change filament.
