I hate using normal scrapers because they scratch the 3D printer bed, and plastic scrapers are not strong enough, so I made this scraper so the tip of the blade never touches the bed, but it gets very close to be effective removing the plastic attached.

It uses the Bambu Lab blade and screws.

You also need an additional M3x20mm screws with washers and lock nuts.

My original design had a fixed height. This upgraded version is adjustable so it can accommodate slight differences to the blade tip angle that can have small variations from each batch.

The assembly is really easy with washers at the ends and the lock nut keeping the screws with a slight pressure. The hard part is adjusting the height of the blade to keep it at a perfect angle and level.

I also made an optional holder that uses 7x5mm magnets.

The design is very compact so it can be manipulated inside small spaces like inside the printer.
