3lb grapnel style anchor for float tube fishing

prusaprinters

<p>I needed a small anchor while float tube fishing in the harbor to hold me from drifting due to small currents (tides) and light breezes. After a little research, a 3 lb anchor seemed to be about right for this.</p> <p>Having several 1 1/2" pvc (~40 mm ID) pipes laying around I thought about 18" section filled with concrete would work fine. Since the harbor is mostly sand bottom, I added some legs to grab the bottom a little better.</p> <p>I glued the bottom cap into the pvc pipe using gurilla glue. I mixed up concrete and poured it into the tube, filling it almost to the top, allowing room for the printed top cap. I let the concrete set for 1 day before gluing on the top cap.</p> <p>The legs are hinged onto the bottom cap ears using 1/8" nylon bolts and nuts.</p> <p>I use a 50' line to tie the tether the anchor to the float tube. The harbors are usually 25-35 feet in depth.</p> <p>I store the anchor in the arm of the float tube. The legs are folded onto the main body.</p> <p>The 4 hinged legs on the bottom cap manually expanded before dropping it in the water.</p> <p>I was asked "why do this when you can buy an anchor off amazon for ~$12.00"?</p> <ol> <li>I had the materials already.</li> <li>I get something exactly what I want.</li> <li>Metal and saltwater don't like each other. This will never rust.</li> <li>Because I just like doing DIY stuff.</li> </ol> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Ultimaker</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ultimaker 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>200</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100</p></div> <p><strong>Filament:</strong> inland PETG clear</p> </p></p></p> Category: Sport & Outdoors
