The prompt
Create a detailed 1:1 CAD drawing of custom rear swingarms for the Kugoo G2 Pro 2020 electric scooter. The swingarms must be designed to fit a KuKirin G4 hub motor instead of the original motor. Keep all mounting points compatible with the Kugoo G2 Pro frame and rear suspension, but modify the motor mount and axle slots to match the KuKirin G4 motor dimensions. The design should be strong enough for high-power use and suitable for CNC laser cutting from 8 mm steel. Include all dimensions, hole diameters, tolerances, and export the drawing in DXF, STEP, and PDF formats.
