Any Angle Clamp helper

prusaprinters

<p>I recently needed to glue together many pieces of wood at many different angles (usually obtuse angles). I found it difficult to find a proper clamping setup that was stable for most of these joints, so I made these.</p> <p>These tools should allow you to apply clamping pressure perpendicular to almost any joint. My strategy was:</p> <ol> <li>Use a machinist square to drop a perpendicular line to the edge(s) you intend to glue</li> <li>Clamp the clamp-helper to your workpiece(s) so that the perpendicular line you found intersects the round portion of the clamp-helper. (This may mar soft wood, I'm sure you could use some sort of rubber or scrap wood as a buffer between the clamp-helper and your workpiece)</li> <li>Clamp the joint using the round portion of the helper, thus applying force perpendicular to the mating surfaces.</li> </ol> <p>It is absolutely still finicky, but when you find a good positioning of the clamp-helper, the joints are rock solid.</p> <p>I printed these pretty beefy:</p> <ul> <li>PETG</li> <li>50% infill</li> <li>5 walls</li> <li>5 bottom/top layers</li> <li>0.4mm layer height (this dropped the print time of the smaller clamp-helper to just under 3 hours)</li> </ul> <p>That said, I did about 20 joints like this, and these things never flinched, no matter how hard I tried to squeeze them.</p> <p>Large measures about 6" end to end and Small measure roughly 4".</p> <p>Though picture includes a solid-fill end for the large model, both models have a hollow end as this was found not to impact strength and removing it decreased printing time.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>TEVO</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Tarantula</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>0.4mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>50%</p></div> <p><strong>Filament:</strong> Generic PETG <br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Tested with:</p> * 5 walls * 5 bottom/top layers </div></p></p></p> Category: Hand Tools
