About this 3D model

I always ruined my print beds with my metal scrapers. So I decided to design a scraper, that uses a 3D-printed blade to avoid the risk of scratching my beds. If your blade gets worn out or you want a new color just come to my account and download the “Blade” file. My name is Laurin and I'm a student. please download the files, then I want to earn these “Makerrewards”. Due to I have no income, I can't afford a new printer, but I really need an upgrade. Please help me out, Laurin
