For a long time, me was hesitant to use a razor blade to remove small objects from the print bed. Occasionally, I've had prints where objects broke off after the first layer. Removing this layer on the Cryogrip buildplate from BiQu is very difficult. The adhesion is so strong that even after cooling and various bends, it's impossible to remove. Me carefully tried using a razor blade, and it didn't damage the buildplate.

Me can't find any square raiser blades in my local store, only ones with rounded edges. So, me needed a scraper that could accommodate these.

To further enhance security, I've added three holes for 5x2 magnets. The handle is secured with two M3x8 screws
