Printbed Scraper / Putty Knife — M50 mm, honeycomb handle

🧩 Description / Design Concept

A 50 mm printbed scraper with a medium-size ergonomic handle and a honeycomb core to reduce material while staying rigid. Designed primarily for cleaning 3D printer beds (removing parts and leftovers) but also very handy as a plastic putty knife/scraper for DIY, art and household tasks that require scraping or smoothing surfaces.

An added bottom chamfer makes it easier to pop the tool off the bed after printing.

🖨️ Printing orientation & tips

Print flat on the bed with the scraper blade face down (as modeled). This gives a straight, strong working edge and a comfortable handle contour.

Adhesion: PEI smooth or textured sheet with glue stick or another adhesion aid recommended.

No supports should be required in this orientation.

🛠️ Recommended settings (scrapers/spatulas)

First layer: 0.24 mm

Next layers: 0.16 mm (good balance of speed and a sharp edge)

Bottom layers: 5

Top layers: 5

Walls / perimeters: 5

Infill: 20% (Honeycomb or Gyroid – honeycomb matches the design intent)

Top/Bottom pattern: Concentric for smooth working faces

Perimeter engine: Arachne / variable line width if available

Material: PETG or ABS/ASA recommended for durability and a bit of flex; PLA is possible but will wear and chip faster under repeated scraping

📝 Notes

Handle size: Medium – comfortable for most hand sizes.

Effective scraper width: 50 mm working edge.

Great way to use up the last meters of filament left on a spool.

After printing, you can lightly sand or deburr the scraper edge (e.g., 400–600 grit) for an even smoother action.

For very stubborn parts or heavy use, stick to PETG/ABS with 5 walls and avoid prying too aggressively to protect both the bed and the tool.

🔧 Usage & handling

Use the flat edge low and parallel to the print surface; slide under the part instead of prying straight up. Works well on glass, PEI sheets, and tapes when used with care. Also useful as a general plastic scraper/putty knife for paint, caulk, stickers and craft materials.
