I print a lot on the Textured PEI and didn't want to damage it with the Bambu scraper with the metal blade, and the fully plastic scraper that's included was too flimsy. I made my own that was somewhere in between for fun. The blade is smaller since I mostly use it to remove the flow calibration line stuff. It's also thicker, less flimsy, and has a longer handle.
I printed it with PLA with the 0.20mm Strength profile and it seems to work fine for my uses (PLA and PETG on the Cool, Engineering, and Textured PEI plates).
The one in the pictures has a logo that isn't included in the public version since I doubt that people want some weirdo's logo on something they're printing for themselves.
