Corner Scraper — 90° & 120° angles (also for printbeds)

🧩 Description / Design Concept

Dual-ended corner scraper with 90° and 120° working edges. Perfect for getting into tight corners on walls, tiles, windows, trays, boxes, tubs – and also very handy on a 3D-printer bed for lifting brim/ooze out of corners.

A lightweight honeycomb handle keeps the tool rigid while saving material and gives a comfortable grip. Also works as a plastic scraper/spatula for general DIY and cleanup tasks where you don’t want to scratch the surface.

🖨️ Printing orientation & tips

Print flat on the bed, with one scraper face down. This gives straight edges and a strong spine 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

Perimeter engine: Arachne / variable line width if available

Material: PETG / ABS / ASA recommended for toughness and slight flex; PLA is possible but will wear/chip faster with heavy use

📝 Notes

Use the 90° end for standard right-angle corners, and the 120° end for more open angles and chamfered corners.

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

Also useful on printbeds: slide the scraper low and parallel to the surface to lift skirt/brim or residue without gouging glass/PEI.

🔧 Usage & handling

Apply force gradually; let the wide plastic edge do the work instead of levering hard at a point. Ideal for removing caulk, paint, stickers, resin, dried filament ooze and similar materials from corners and edges.
