Rounded Bambu Scraper Handle

修改了bambu Lab的刮刀，單色且讓造型更加圓弧中間簍空處可以壁掛，同時可以減少耗材使用，強度測試上感覺跟原本的差異不大。Modified the Bambu Lab scraper to a single-color design with a more curved shape and a hollowed-out center for wall mounting.This adjustment reduces 3D filament usage while maintaining similar strength based on testing.Boost MePlease Press this button to give me a Boost!
