20ml Grease Syringe Efficient Nozzle (2.2mm Opening · No-Support Fast Print Version)

🔧 Pain Point Terminator! Say goodbye to the struggle of "hard to push" original nozzles
A special replacement grease nozzle designed for standard 20ml syringe barrels! Original accessories often cause extrusion jams and require effort due to small openings or unreasonable flow paths. This model significantly reduces resistance through a precise 2mm grease outlet + streamlined internal cavity optimization, making grease extrusion smooth and even, and easy to operate with one hand～

✨ Design Highlights
✅ No supports structure: Optimized overhang angles, zero supports for printing, saving time and material, beginner-friendly
✅ Fast printing: Lightweight design, single piece takes about 14 minutes (0.2mm layer height), print and use immediately
✅ Tight fit: Internal threaded interface compatible with mainstream 20ml plastic/glass syringes
✅ Practical opening: 2mm aperture balances flow and pressure, prevents dripping and clogging, precisely controls grease injection amount. If you find the aperture still too small or extrusion difficult, you can bevel the outlet.
