<p><font size="3" color="red"> *Update:*</font><b>I've modified the body of the Venturi Pump to provide a solid structure, as it had previously snapped twice in the same spot.</p> <p><font size="3" color="red"> *Revision Details:*</font><b> Revision 4.6 includes filled-in webbing and an extended suction inlet, with a slight increase in length. This update was made on May 27, 2020.</p> -------------------------------------------------------------- -------------------------------------------------------------- <big><b>Enhanced Venturi Pump Design with Additional Features</big></b> <b>Features:</b> - I've extended the suction inlet and reduced its diameter to accommodate 3/8" tubing snugly. - Designed an O-Ring seal to connect it with a quick connector. - Repaired the original STL file from the creator. <b><font size="3" color="red">!Read Before Printing!</font></b> 1) Use PETG for the main part to ensure strength under pressure, as it will be subjected to pressure. 2) Apply TPU on the O-Ring to allow it to compress. 3) Orient the part so that the threaded side faces down and use supports during printing. <b><font size="3" color="Green ">!Pre Assembly!</font></b> 1) Coat the printed part with PVC cement to prevent leaks when under pressure. <b><font size="3" color="blue">!Part Assembly!</font></b> 1) Apply Teflon tape to all male threads. 2) Heat up 3/8" tubing using a heat gun or lighter and push it into the suction port. 3) Connect/screw in the pieces. 4) Place the suction tube into your nutrient container, ensuring the line is submerged under water, and turn on the water. <b>Parts Used:</b> <a href="https://amzn.to/2AcN71d"target="_blank">3/8" Tubing</a> <a href="https://amzn.to/2X3ydDM"target="_blank">Gardena Quick Connector</a> <a href="https://amzn.to/2XupoS9"target="_blank">PVC Cement</a> <a href="https://amzn.to/3c5IlQu"target="_blank">Teflon</a> <a href="https://amzn.to/3c5XYHE"target="_blank">PETG</a> <a href="https://amzn.to/3d4d2Xt"target="_blank">TPU</a> -------------------------------------------------------------- -------------------------------------------------------------- <big>Like, share, follow, and don't forget to post a picture if you build one!
