Replacement Lawn Mower Speed Control

The throttle control on my parents' Mountfield RM45 lawn mower broke, and they were planning to buy a replacement. After searching online, the only available part I found cost £25. Instead, I decided to model and 3D print the part myself. This saved us both money and time, and it's always satisfying to print a useful part. Since others might encounter the same issue in the future, I’m sharing this model to help anyone else who finds themselves in a similar situation.
