<p>This cap lets you add an eyelet to your PET Geocaching container by gluing it onto the bottle cap.&nbsp;</p><p>This model accepts bottle caps up to a diameter of 30 mm. Instead of a model with printed threads, this method provides a better, watertight seal by using a standard bottle cap for PET bottles which is being glued into the printed cap.<br>Any glue/resin for plastic should work, however, we achieved good results using Tangit PVC-U glue which we had lying around.</p><h3>Print instructions:</h3><ul><li>Place the model <strong>upright</strong> (1st picture) on the print bed.</li><li>Print<strong> without rafts and without supports</strong> if your filament supports bridging over a length of 30 mm (PLA worked fine). If not, you only need supports on the print bed. The eyelet is designed to print without supports.</li><li>I printed on black PLA and didn't have any issues with the caps breaking under direct sunlight after 6 months. However, printing in PETG or ASA/ABS might be more suitable for prolonged outdoor use.</li></ul><h3>Assembly:</h3><ol><li>Screw your bottle cap onto a PET container. This allows for better positioning of the bottle cap inside the print.</li><li>Spread adhesive on the inside of the print. Insert and twist the bottle cap to ensure even spread of the glue.</li><li>Let the adhesive set before opening the container. There should be no movement between bottle cap and print.</li><li>Thread a fence wire through the eyelet and bend it into your desired shape (e.g., a hook).</li></ol>
