Upgrade your workshop dust-collection system with this professional, high-performance 3D-printed Blast Gate, engineered for maximum suction, minimum leakage, and effortless usability.

Designed with precision-fit sealing ring grooves, this blast gate offers exceptional air-tightness, ensuring you maintain virtually full suction power throughout your system. The internal geometry is smooth and optimized to prevent clogging, while the slide mechanism moves freely and reliably without wobble.

Also available as a 50mm version: [https://makerworld.com/de/models/2145654-ultimate-workshop-blast-gate-50mm-version#profileId-2324629](https://makerworld.com/de/models/2145654-ultimate-workshop-blast-gate-50mm-version#profileId-2324629)

Why this blast gate stands out:

• Zero-leak design: Grooves for 3.5 mm sealing rings (outer Ø 42–47 mm) create an exceptionally tight seal.
• No supports needed: Every part is optimized for clean, support-free printing.
• Lightweight & filament-efficient: Complete assembly uses only ~110 g of filament.
• Sturdy & workshop-ready: Thick, reinforced walls ensure long-term durability in tough shop environments.
• HT40 compatible: Fits standard HT40 pipes; the slightly conical connector grips firmly with a simple push-fit—no clamps required.
• Easy assembly: Uses only 3× M4×15 mm screws and 3× M4 nuts, plus two sealing rings.
• Smooth slide action: Carefully tuned tolerances allow the gate to operate effortlessly while maintaining a perfect seal.
• Clog-resistant internals: Designed to avoid dust buildup around the slider.

Recommended print settings:

• Material: PLA, PETG, or ABS (PETG recommended for heat-resistance in warm workshops)
• Layer height: 0.2 mm
• Perimeters: 2 (3 for extra stiffness)
• Infill: 15% (grid or gyroid)
• No supports required
• Smooth PEI print plate is recommended for the slider plate to ensure smooth operation

If you want a reliable, tough, and highly efficient blast gate that prints quickly and installs even quicker, this design is the perfect upgrade to your dust-collection system. Enjoy cleaner air, better suction, and a smoother workshop workflow!
