<p>I am converting a passive subwoofer to active, and so got this amplifier from amazon:<br/> https://smile.amazon.com/gp/product/B01N5DGK37/</p> <p>It comes as a bare board, so I needed a case, this is it.</p> <p>The first run fit pretty well, I had to use a round file to cleanup the wholes and the 3.5mm jack needed to come a bit towards the volume knob. the 4 posts for the mounting screws needed just a touch more space too, but they did work. I made really minor tweaks to these in the models and re-uploaded. but it was useable as it was originally.</p> <h3>Print instructions</h3><h3>Category: Audio Print Settings</h3> <p><strong>Printer Brand:</strong> FlashForge</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2F3xKW3">Creator Pro</a></p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> .2</p> <p><strong>Infill:</strong> 35%</p> <p><strong>Filament:</strong> AMZ3D PLA Bronze<br/> <strong>Notes:</strong></p> <p>I used 3 bottom, 3 tops and 3 outer layers. I don't think its especially sensitive though.</p> <h3> Post-Printing</h3> <p>May need to file the knob holes a little bit to fix the top of the circle depending on how well your printer can print overhangs on circles.</p> <p>Also when installing the board its best to tightly screw down the volume knobs nuts to "set the plastic positions" then loosen them back up, put in the 4 mounting screws and then re-tighten the volume knob nuts.</p> <h3> How I Designed This</h3> <p>Designed in FreeCad</p>
