<p>Wilbur the Washing Whale is a timer for handwashing. He is designed to sit on the edge of a sink or tub. Simply fill the basin in his tail with water and he will swim and spout for 25 to 30 seconds. He also makes a great bath toy!</p> <p>Great for kids and adults who have grown tired of singing happy birthday to themselves.</p> <p> <figure class="media"> <oembed url="https://youtu.be/AM41xiLBsSE"></oembed> </figure> </p> <h3>Print instructions</h3><p>Wilbur has 8 different parts, all can be printed at a layer height of 0.2 mm with a 0.4mm nozzle. Additionally, you will need superglue or a similar adhesive to assemble the full print.</p> <p><strong>Printing Overview</strong><br/> All parts have already been oriented in the best position for printing. Excluding the fins, all parts can be printed without supports.</p> <p>We recommend printing at a layer thickness of 0.2mm or lower with a 0.4mm nozzle. Unless otherwise noted a 15% infill was used for all parts. The settings here were optimized for prusament PLA but other materials should work as well.</p> <p><strong>Printing Part-by-Part</strong><br/> Axle - Print flat on side of the hexagonal axle. No supports needed. For added strength print with 100% infill though 15% infill works fine.</p> <p>Water Wheel - Print so that the wheel lays flat on the build plate. No supports needed.</p> <p>Fins - Print in the orientation provided with the default support settings in Prusa Slicer.</p> <p>Tail Sheath - Print so that the tail is oriented up with the flat circular ring sitting on the build platform. No supports needed.</p> <p>Head Spout - Print so that the face is oriented up with the flat circular ring sitting on the build platform. No supports needed.</p> <p>Base - Two separate .stl files are provided for the base. The 'supported' file has several small manual supports that support the ring where the headspout attaches to the base. These can be easily removed with a pair of plyers after printing. Otherwise this file needs no additional supports. The base should be printable without these supports which is why we also provided the unsupported file.</p> <p><strong>Assembly</strong></p> <ol> <li><p>Clean up each part separately. Remove burs, strings, and sand down any rough patches, particularly at places where the parts are to be joined.</p> </li> <li><p>Slide the waterwheel into the base using the long slot on the base. The cups (C shaped pieces) on the waterwheel should be oriented facing up on the part of the water wheel that enters the base first.</p> </li> <li><p>Slide the axle through the holes on the side of the base and into the hexagonal slot on the waterwheel and through the hole on the other side of the base. Adjust the position of the wheel so that it is centered on the axle.</p> </li> <li><p>Attach the fins to the axle so that they are oriented in opposite directions (see render). If they are somewhat loose, you can super glue them in place but before gluing them be sure that the waterwheel is correctly oriented.</p> </li> <li><p>Place the basin in the hole at the top of the base, then slide the tail sheath over it. You can then glue these pieces in place or leave them unglued.</p> </li> <li><p>Squeeze a few drops of superglue around the circular base of the headspout then slide it into the slot on bottom front edge of the base. Making sure to orient the head so that it is correctly centered. You can tape the head in place while the glue dries if desired.</p> </li> </ol> <p><strong>Usage</strong><br/> See video in description.</p> <p>Pour water up to the line in the basin and watch as Wilbur spins and spouts for 25 to 30 seconds. If the wheel doesn't start spinning immediately give it a little nudge.</p>
