2-Liter Soda Bottle To 0.25-Inch ID Tube Adapters

prusaprinters

<p>I grow tomato plants indoors during the winter, and use these adapters to help water the plants slowly via a 2-liter soda bottle filled with water. This set includes single, double, triple, quad, and six-outlet versions.&nbsp;</p><p>Works best with 0.25" (or 6mm) inner diameter (ID) tubing. For best results, soak the end of the tubing in hot water, slip over the adapter nub, and secure with a zip tie behind the nub.&nbsp;<br><br>To prevent leaks, cut a small washer out of thin EVA / Craft foam, or a small rope of modeling/polymer clay pressed into the bottom of the adapter under the threads. I use both methods, and each works just fine.&nbsp;</p><p>For ease of use, download and print my <a href="https://www.printables.com/model/161071-2-liter-soda-bottle-clamp-mount">2-Liter Bottle Clamp Mount</a> to hold the 2-liter bottle securely in place as shown in the images.&nbsp;<br><br>Tested to work with the following tubing:&nbsp;</p><ul><li>JoyTube ¼" ID Silicone Tubing - <a href="https://amzn.to/379qGuq">https://amzn.to/379qGuq</a>&nbsp;</li><li>Rollerflex ¼" ID Crystal Clear Vinyl Tubing - <a href="https://amzn.to/3uOudX9">https://amzn.to/3uOudX9</a>&nbsp;</li><li>Outfandia ¼" ID Irrigation Tubing - <a href="https://amzn.to/3iWKAeP">https://amzn.to/3iWKAeP</a>&nbsp;</li><li>Feelers Drip Irrigation ¼" OD Switch Valve - <a href="https://amzn.to/3LD5I69">https://amzn.to/3LD5I69</a>&nbsp;</li></ul><p><br><strong>*Note:</strong> &nbsp;As these models need to be printed watertight, and quite sturdy, I recommend printing with 6 perimeters, and 5-6 top and bottom layers.&nbsp;<br><br><strong>*Note:</strong> &nbsp;It's important to use supports when printing these models as the threads, and nubs will not print correctly without supports. If using Prusa Slicer use support enforcers where needed, to avoid support material from being printed in the water passageways. The included G-Code file contains all the models on one platter and the necessary support enforcers.&nbsp;<br><br><strong>*Note:</strong> This post contains Amazon Affiliate links that support The Makers Workbench via a small commission from any sales they help generate.</p><p><strong>Design File Included:</strong> .stl .f3d, step, .skp and obj files.
