Third Hand Soldering Helper

prusaprinters

<p>This is my attempt at building a simple 3rd hand for soldering. You can read my blog post at <a href="https://www.splitbrain.org/blog/2018-10/21-diy_third_hand_soldering_helper">https://www.splitbrain.org/blog/2018-10/21-diy\_third\_hand\_soldering\_helper</a></p> <h3> Needed materials:</h3> <ul> <li>about 1m Aluminium wire (5mm diameter), cut to two 30cm and two 20cm pieces</li> <li>4 51mm alligator clamps</li> <li>1 300x100x2mm perforated metal sheet (only thickness matters) - they are sold to connect wood beams</li> <li>2 10x2mm magnets (for the optional bowl)<br/> Assembly</li> </ul> <hr/> <p>The holes in the metal sheet are probably not perfect aligned with the corner pieces. Simply drill them a bit bigger. I used a 8mm drill.</p> <p>Print four corners, four clamp holders (use brim) and optionally one bowl.</p> <ul> <li>Fit the corner pieces on the metal sheet</li> <li>push in the wire (make a slight L-shape and rotate the wire to get it in easier)</li> <li>put the clamp holders on the wire (might need some light sanding on the wire)</li> <li>put the clamps into the holders</li> <li><p>push the magnets into the bowl (use glue if too lose - I did not need any)<br/> Everything should work press fit - I didn't use any glue.</p> <p>Tinkercad Sources</p> </li> </ul> <hr/> <ul> <li><a href="https://www.tinkercad.com/things/9ijTN3aAFxS-3rd-hand-corner#/">Corner Piece</a></li> <li><a href="https://www.tinkercad.com/things/7Eu86ePPTH4-3rd-hand-magnet-bowl#/">Magnet Bowl</a></li> </ul> <h3>Print instructions</h3><p><strong>Printer Brand:</strong> Prusa<br/> <strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">i3 MK3</a><br/> <strong>Rafts:</strong> Yes<br/> <strong>Supports:</strong> No<br/> <strong>Resolution:</strong> 0.1mm<br/> <strong>Infill:</strong> 20%<br/> <strong>Filament:</strong> off-brand PLA white</p> <p>Rafts are needed for the clamp holders only.</p>
