Whetstone Bridge

prusaprinters

<p>First iteration of a 3D printable whetstone bridge, for manual knife sharpening over the sink.</p> <p>There are similar designs, where this one differs most is the use of metal channel rather than threaded or linear rods. I went with aluminum channel, mostly because it was available, but also shouldn't need to deal with rust.</p> <p>Provided you have long enough channel sections, this should fit any sink.</p> <p>The stone clamps are 75mm wide, with a 10mm lip, should work with most common stone sizes.</p> <p>Materials list:</p> <ul> <li>4 @ 1/4-20 x 1.5" Hex bolt</li> <li>4 @ 1/4-20 Hex nut</li> <li>2 @ 5/8" wide x 1/2" Channel (at least 2" longer than your sink)</li> </ul> <p>Print list:</p> <ul> <li>4 Knobs</li> <li>4 end caps (optional)</li> <li>2 copies of each of the sink/stone base/top</li> </ul> <p>The bolt holes through these parts have a tapered point, if you align these with your positive Z direction (up) in your slicer, you should not need supports in these sections (They are quite annoying to remove otherwise). The 'legs' of the clamp-sets will still need support however.</p> <p>I opted to print these with 5 perimeters with about 20% infill. Could possibly do with slightly less. Will have to see how it holds up to abuse.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Artillery Sidewinder X1</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>Doesn't Matter</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>200</p></div> <p><strong>Infill:</strong></p> <p>20</p> <p><strong>Filament:</strong></p> n/a PLA </p></p> Category: Kitchen & Dining
