Dimensions: The inner radius of this protective ball is 18mm, the hole is 12mm.
If your bike tips over it will probably land on the brake handle and scratch it.
Print it with a flexible material (TPU) and slip it over the ball.
I've sliced it in Sovol Cura, normal setting (0.15 mm layer height), 220C nozzle, 60C bed, 40mm/s speed, no supports.
