Sprinkler with 3/4" thread - no moving parts

prusaprinters

<p>This is a minor remake of the <a href="https://www.thingiverse.com/thing:3068655">https://www.thingiverse.com/thing:3068655</a> by 3DPNoob. Thanks for the great design!</p> <p>After printing out multiple other sprinklers with moving parts with no great success, since I am only running a rainwater pump with is delivering max. 2.5 bar, this is the first sprinkler which really covers a big area even at low water pressure. If you mount it on a pole, you can reach easy a 6-8m diameter coverage with only 2.5 bar. Higher pressure should provide an even bigger range.</p> <p>I did the remake since the initial sprinkler has no attachment and you have to use the hose for that. Now you can just screw the base plate to whatever surface (e.g. a pole) and just attach the sprinkler to the base plate.</p> <p>This comes in handy since a lot of people are using Gardena style hose connectors. Therefore I first tried to directly print a Gardena connector, but the tolerances of the available connectors lead to some minor leaking and you always need the additional rubber seal.</p> <p>So I decided to also model a sprinkler with an additional 3/4" thread (<a href="https://www.thingiverse.com/thing:2811608">https://www.thingiverse.com/thing:2811608</a>) so you just an attach standard and Gardena 3/4" hose connectors. If you want to have a female 3/4" connection, just use the base design <a href="https://www.thingiverse.com/thing:3068655">https://www.thingiverse.com/thing:3068655</a> part.</p> <p>And if you want to add your own remake just use the included FreeCAD Model</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anet A8 Bowden</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>0,2</p></div> <p><strong>Infill:</strong></p> <p>50</p> <p><strong>Filament:</strong></p> Surreal PLA <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>....unlike the initial model, I was using just 50% infill which should be enough, even for the mounting part...</p></div> Post-Printing ============= <p>Just glue the the sprinkler head and the threaded part together. I used plenty of standard superglue.</p> <h3>How I Designed This</h3> <p><strong>FreeCAD</strong></p> <div><p>the model is included.<br/> As already mentioned in my other models, I supper-positioned STL models and FreeCAD parts, did a multi select and exported them as a combined STL (Boolean merge). <p>You should also find the Gardena adapter with the not so good tolerance and the the prism based mount in the file which you can ignore..</p> </p></div></p></p> Category: Outdoor & Garden
