I apologize for my drawing skills, I was having a hard time trying to show the change I want with a drawing. But essentially I just want about 4 cm added to the top, before the infill with the small diameter hole starts, so the blades can still sit within the hilt without being partially extended when not in use. In other words the original end-caps inside area added at the top of yours, so that functionally they are the same until you reach the parts that you changed for me.
