<p>Years ago, when first learning to solder, I found some jigs like this:<br><a href="http://www.fortex.co.uk/product/pcb-assembly-jig-pcsa1/">http://www.fortex.co.uk/product/pcb-assembly-jig-pcsa1/</a></p><p>But they were all ludicrously expensive (200+ USD), so I never really though much of them until came upon this:<br><a href="https://www.nutsvolts.com/magazine/article/september2011_Collier">https://www.nutsvolts.com/magazine/article/september2011_Collier</a></p><p>It was DIY, and much cheaper, only ~80 bucks in materials, though that still seemed like a lot, but now with 3d printing I could easily make something sturdy enough while being 1/10th the cost, less than $8.</p><p>I hope you find it useful!</p><p>&nbsp;</p><p>Print Size: 245mm x 205mm x 25mm (easy to print on mk3)</p><p>Included gcode is for prusa mk3</p><p>&nbsp;</p><p>Required Hardware:</p><p>4x M4 Hex Nuts</p><p>4x M4 Bolt (Hex Head) (Greater than 25 mm, Less than 40mm)</p><p>Superglue</p><p>25mm+ thick foam cut to size</p><p>&nbsp;</p><p>Print:</p><p>1x pcb_holder_frame</p><p>2x (or 4x) pcb_holder_arms</p><p>4x pcb_holder_nut_holder</p><p>4x pcb_holder_screw_grip</p><p>&nbsp;</p><p>&nbsp;</p><p>Assembly:<br>&nbsp;</p><ol><li>Glue nut_holder onto screw_grip</li><li>Insert M4 Hex Nut into each of the 4x nut_holder</li><li>Insert M4 Bolt into each of the 4 corners of the frame</li><li>Place 1 or 2 arms (depending on pcb thickness) between the M4 Bolts on opposite sides of the print</li><li>Screw the combined nut_holder and screw_grip onto the M4 Bolts</li></ol><p>Assembly complete!</p><p>Use:</p><ol><li>Place the PCB between the two arms with the edges inside the angled grove cut into the arms and push them together</li><li>Check that the top (where the parts will stick up) is facing the inside of the frame, away from the screw_grips</li><li>Lock the arms in place using the screw_grips</li><li>Assemble PCB, &nbsp;(Recommended to make multiple passes from shortest to tallest components, grouping similar heighted components together)</li><li>Insert foam to hold parts in place</li><li>Flip over and solder parts in place</li><li>Repeat steps 4-6 until all parts have been added</li></ol>
