Keep your workshop clean and efficient with this versatile assortment of rectangle dust collection hoods. Engineered for maximum surface area coverage, these hoods are perfect for CNC routers, table saw setups, workbench cleanup zones, or custom dust-collection routing. Each hood features a robust flat mounting flange secured by eight 0.16" mounting holes for a rock-solid installation.

Available Versions

  • Standard Straight (2.5” Port): Ideal for standard shop vac hoses and smaller power tools.

  • 45-Degree Angled (2.5” Port): Perfect for tight spaces or directional hose routing where straight clearance isn't an option.

  • Standard Straight (4” Port): Built for larger main-line dust collection systems and heavy-duty extractors.

  • 45-Degree Angled (4” Port): Heavy-duty directional routing for large-diameter mainline hoses in tight spaces.

Print Settings

Since these are functional workshop tools that frequently handle heavy hoses and tension, follow these guidelines for maximum durability:

  • Orientation: Print with the flat mounting side directly on the bed. No supports required!

  • Material: PETG, ABS or ASA highly recommended for workshop impact resistance and thermal stability. (PLA can work for light duty, but may creep or warp under constant hose tension or warm shop conditions).

  • Layer Height: 0.12mm to 0.20mm

  • Infill: 20% or higher (Gyroid or Grid pattern recommended).

  • Perimeters / Walls: 4 or more walls (Pro-tip: Extra perimeter walls add significantly more functional strength to thin-walled parts than high infill percentages alone).
