Here's a Trimmer That Uses Nylon String to Cut Grass Made with a 3D Printer You can use this trimmer to cut grass and weeds, but it needs a more powerful motor and a different wire connector that can handle more current. A great option for the motor is the RS-550 from an old cordless drill, which spins at 20,000 RPM. Parts: * 3 parts made with a 3D printer (2 for the head and 1 for the button box) * 2 M3x8 screws * 2 M3x15 screws * 1 M3x18 screw * 2 wide washers that fit onto an M3 bolt * 5 nuts that fit onto an M3 bolt * Some nylon string with a diameter of 2-3 mm
