Corner Scraper — 90° & 75° angles (dual-ended)

🧩 Description / Design Concept

Dual-ended corner scraper with 90° and 75° working edges. The 90° side is ideal for standard inside corners (walls, tiles, boxes), while the 75° side reaches into tighter or beveled corners that flat tools miss. Also very handy on a 3D-printer bed for cleaning edges, removing brim and residue without scratching the surface.

A lightweight, reinforced body keeps the tool rigid while saving material, and the long handle gives good leverage for controlled scraping.

🖨️ Printing orientation & tips

Print flat on the bed, with one scraper face down. This maximizes edge straightness and strength along the length of the tool.

No supports needed in this orientation.

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

🛠️ Recommended settings (scrapers/spatulas)

First layer: 0.24 mm

Next layers: 0.12–0.20 mm (use 0.12 mm for sharper working edges)

Bottom layers: 5

Top layers: 5

Walls / perimeters: 5

Infill: 20–25% (Honeycomb or Gyroid)

Top/Bottom pattern: Concentric for smooth scraper faces

Material: PETG / ABS / ASA recommended; PLA is possible but will wear and chip faster under heavy use

📝 Notes

Use the 90° end for classic right-angle corners, and the 75° end for narrow or slanted corners and transitions.

After printing, lightly deburr/sand the working edges (e.g. 400–600 grit) for an even smoother action.

On printbeds, slide the scraper low and parallel to the surface—avoid prying straight up to protect both the bed and the tool.

🔧 Usage & handling

Ideal for removing caulk, paint, stickers, dried filament, adhesive and other residues from corners and edges in bathrooms, kitchens, workshops and around 3D printers.
