After trying to make a casting mould of my original throttle with silicone glue (and destroying it due to the solvents) I had a small issue with my ABS filament and the original part broke when I installed. Because of the pandemic, I can't buy anything else, so I tried another model of the throttle, which hasn't aligned with the screw holes of my scooter. But I liked the design of them and thought it would look nice together, so I joined the two. Hope it helps someone else.
