Description

This scraper was designed as a safe alternative to metal tools, eliminating the risk of damaging your build plate while maintaining excellent performance.

It uses standard plastic blades, allowing precise removal of brims, residue and small imperfections without scratching smooth or textured surfaces.

The geometry is clean, solid and ergonomic, providing a confident grip and controlled pressure during use.

A key feature is the Easy Blade Swap system, enabling fast and secure blade replacement without tools.

The included holder keeps the tool upright, organized and always accessible next to your printer.

Assembly is flexible and adapts to what you already have available: glue, M2.5 screws from the original Bambu scraper, or M3 screws from the filament holder.

Beyond 3D printing, this tool works great as a general-purpose scraper, ideal for removing adhesive, lifting labels and cleaning delicate surfaces.
