<p>UPDATE 2021-04-30: Added a simple cap to cover the motor terminals.</p> <p>This is a wide mouth Mason jar lid with mounting holes for a cheap 12V peristaltic pump. I will use this as part of an automated container garden.</p> <p>The pump I used is https://www.amazon.com/gp/product/B075VN1QZM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1</p> <p>The pump attaches with M3x12 screws and M3 nuts and washers. The output tube comes out through a rubber ring designed for a nominal 5/16" hole (sorry to mix metric and American units, but it's what I had on hand). Or skip the rubber ring and it will double as a vent hole (personally I did not find this necessary).</p> <p>Lid is a remix of <a href="https://www.thingiverse.com/thing:19105">https://www.thingiverse.com/thing:19105</a></p> <p>I had some problems with the original wide mouth jar lid STL so I re-rendered it in OpenSCAD and have included that as well.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Prusa MINI+</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>150</p></div> <p><strong>Infill:</strong></p> <p>100</p> <p><strong>Filament:</strong></p> Overture PETG <p>Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Be careful that you get good layer adhesion. My initial prototype (in PLA) cracked when I screwed it on, I think because my printing temperature was too low and the layers didn't adhere well. You might want to avoid screwing it on tight regardless. Infill percentage probably doesn't matter; even with only 2 perimeters there is almost no patterned infill.</p></div> </p></p> Category: Outdoor & Garden
