This universal beverage bottle funnel adapter is specifically designed for everyday portioning tasks. It securely attaches a standard funnel to any standard beverage bottle, eliminating the hassle of funnel tipping and liquid spillage during filling—perfect for both the kitchen and the desk!

✅ Key Features and Benefits

• Spill-proof and hands-free: The adapter firmly locks the funnel in place at the bottle opening, so you no longer need to hold it steady. You can easily operate with one hand while dispensing liquids, ensuring no more spills onto the countertop or outside the bottle.

• Universal compatibility: The adapter fits most standard-sized beverage bottles on the market (such as soda and water bottles) and works with commonly available funnel sizes, so there’s no need to buy a specialized funnel—low-cost convenience for effortless portioning.

• Adaptable for multiple scenarios: Whether you’re portioning oil, vinegar, or condiments in the kitchen, cleaning agents or hand soap on your desk, or even powder or liquid filaments for 3D printing, this adapter handles it all—making it ideal for any situation that requires a “funnel + bottle” setup.

• Easy-to-print design: The model features a flat, ring-shaped structure that requires no supports and can be easily printed using PLA filament. Its sturdy, durable construction ensures it retains its shape even after repeated use, so even beginners can achieve successful prints on their first try.

✅ Printing & Usage Recommendations

• Recommended filaments: PLA/PLA+ (the top choice for dispensing room-temperature liquids due to low cost and ease of printing); for oils or cleaning agents, we recommend PETG to enhance corrosion resistance.

• Slicing settings: 0.2 mm layer height, 2–3 wall thickness, 20% infill, and support-free printing to ensure the adapter’s strength and flexibility.

• How to use: Simply slip the adapter over the bottle opening, then insert the funnel into the central hole. The adapter’s snap-lock mechanism securely holds the funnel in place, allowing for stable liquid dispensing. For funnels of different diameters, you can fine-tune the print dimensions as needed.

✅ Applicable Scenarios

• In the kitchen, dispense cooking oil, soy sauce, vinegar, and other condiments—no more struggling to hold the funnel while pouring.

• On the desk, dispense hand soap, dishwashing detergent, and cleaning agents to prevent spills from contaminating the surface.

• Dispense 3D-printing filaments or chemical liquids for more precise and cleaner handling.

• For DIY projects or gardening irrigation, this adapter provides an affordable solution to secure the funnel in place.

Whether you’re portioning ingredients in the kitchen or engaging in desk-side DIY activities, this adapter makes the job easy, keeping your workspace clean and hassle-free!
