• 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.
• HT50 compatible: Fits standard HT50 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
