Universal adapter for Soda bottle and Gardena coupling and rocket fins

prusaprinters

<p>This is an adapter to put fins on a 0.5 - 1.5 liter soda bottle, as well as to mount a Gardena ¾ " faucet coupler.</p><p>You have to put a rubber gasket between the bottle and adapter. (Gardena has such in their product line). The Gardena part already has a rubber gasket and O-ring.</p><p>You can find a launcher based on the Gardena coupler here: <a href="https://www.thingiverse.com/thing:4368014">https://www.thingiverse.com/thing:4368014</a></p><p>Print the coupler with 4 layer walls and 100% infill to make them air tight.<br/>Also a bit of silicone grease will help. See also the post printing instructions.</p><p>I have uploaded 2 types of fins. Pick the largest for larger bottles.<br/>Print the fins horizontally for max strength. (You could try to print the whole device at once, but strength will be much less. The fins will break during a rough landing because of the horizontal layers)</p><p>Be careful when you put pressure on. Keep your distance. Your bottle might explode.<br/>I did not go over 40 PSI.<br/>I also do not guarantee this design or will be liable for any accidents or damages!</p><h3> </h3><h3>Print Settings</h3><p><strong>Printer Brand:</strong> XYZprinting</p><p><strong>Printer:</strong> da Vinci 1.0 Pro 3in1</p><p><strong>Rafts:</strong> No</p><p><strong>Supports:</strong> Yes</p><p><strong>Resolution:</strong> 0.1 mm</p><p><strong>Infill:</strong> 100%</p><h3><strong>Filament:</strong> Profil ABS Black (any color is OK) Post-Printing</h3><p><strong>Post processing</strong></p><p>Carefully remove the supports and sand the adapter after printing.
