scraper with replaceable blades

hello. I present my version of a plate scraper. The scraper has replaceable blades similar to the original scraper from bambulab, however, in my scraper I used trapezoidal blades for knives. the whole thing is screwed together with 2 M3x12mm screws. In order for it to work properly, the sharp corners of the knife should be ground down as shown in the picture have fun printing :)
