Printboard - A prototyping board for electronic circuits

prusaprinters

<p>This model can be used as an inexpensive and configurable breadboard alternative, with the advantage that the components can be soldered in-place.</p> <h3>Print instructions</h3><h3>Important Notes</h3> <ul> <li>You need a 0.25 mm nozzle to print this</li> <li>The electronic connections are not 100% reliable (as long as you don't solder them)</li> <li>Has been tested with DIP-8 packages, resistors, diodes and capacitors</li> <li>For each row of the board you will need a needle pin (preferred) or a nail (with about 1 mm diameter)</li> <li>Currently, power rails are not supported</li> <li>Only PLA has been tested (please let me know if you printed this with another material)</li> </ul> <h3>Configuration</h3> <ul> <li>If you have needle pins with 0.6 mm diameter and want a board with 6 columns on each side and 15 rows than you can use the provided .stl (or .gcode) file</li> <li>If not, install OpenSCAD and download the .scad file. Alternatively, you can clone the <a href="https://gitlab.com/ijkklm/printboard">gitlab repo</a> to get the most recent version<ul> <li>In the .scad file, enter the diameter of the needle pins or nails at the assignment of <code>rod_d</code></li> <li>Scroll to the end of the file and enter the pin counts of the board in the call to 'double_sided_board(...)' (see comments of the module)</li> <li>Render (might take a while) and export .stl</li> </ul> </li> </ul> <h3>Print Guide</h3> <ul> <li>Import the .stl from the previous step into PrusaSlicer</li> <li>Make sure that the extrusion width is set to 0.25 mm</li> <li>Recommended extrusion width for first layer: 0.42 mm (avoids gap infill)</li> <li>Use 100% infill</li> <li>Make sure <code>Detect bridging perimeters</code> is enabled</li> <li>If the print does not stick, decrease first layer speed and increased Bed Temperature for the first layer</li> </ul> <h3>Assembly</h3> <ul> <li>Gently move all the clips with a screwdriver<ul> <li>If the clips break off or do not move independently set <code>Seam Position</code> to <code>Random</code> and decrease nozzle temperature a bit</li> <li>If that does not help the reason may be low quality filament (I have used Prusament after I had trouble with filament of another manufacturer)</li> </ul> </li> <li>Cut off the tip of your needle pins (or nails)</li> <li>Cut them so that they do not stick out when fully inserted (see the small "observation hole" at the center of the board)</li> </ul> <h3>Usage</h3> <ul> <li>You can assemble your circuit as you would do it on a normal breadboard</li> <li>If you are done, you can solder the components to the row connectors. Some of the plastic around the point where you solder will soften/melt, do NOT inhale the fumes</li> </ul>
