As the amount of people entering the hobby increase, there is a growing demand for better and cheaper gardening products. I have also joined in on this new growing hobby and have personally found that commercial horticultural equipment is expensive to purchase; so to combat this, I have embarked on creating a line of 3-D printable hydroponic/agricultural products (all open source of course). The first item that I have created is called a \"Hydro halo drip ring\", and is used to evenly water plants from a central location using a timer and a water pump.\n\n(Picture of completed print will be provided later.)\n\n== Bill of Materials ==\n\n* 3-D Printing filament (i.e. PLA, ABS, etc.) <= That is the only material you need to print this part!\n* SCAD/STL file of the hydro drip ring\n\nScad and STL files available at [https://www.thingiverse.com/thing:577334/#files http://www.thingiverse.com/thing:577334/#files]\n\n== Tools needed ==\n\n* [[Delta Build Overview:MOST|MOST Delta RepRap]] or similar RepRap 3-D printer\n\n== Skills and knowledge needed ==\n\nNothing more than basic 3D printing and altering well commented variables to get desired size required\n\n== Technical Specifications and Assembly Instructions ==\n\nI used Openscad for the model, Cura for the slicer, and Repetier-Host to print the part. Open the.SCAD file in Openscad, and adjust the given parameters to fit your needs. All units are in millimeters{{Clear}}. Note: The hydroponic halo is currently set with a 6\" diameter and can handle a 1/2 inner diameter hose connection.\n\nApproximate print time (assuming original model is left un-altered) estimate: 3 hours 20 minutes\n\n== Cost savings ==\n\n# My design used $3.13 in plastic at $25/Kg (i.e. 125 grams of polymer were used to print this)\n# [http://www.midwesthydroponics.com/6-hydro-halo-water-ring.html|A Commercial Hydro halo like this will cost around 11 dollars]\n# The total estimated savings are therefore approximately 71.54%!\n\n== References ==\n\n{{777 notice}}\n\n{{Page data\n| keywords = 3D printing, farm, gardening, hydroponics, osat, sprinkler, water, ABS, PLA\n| sdg = SDG03 Good health and well-being, SDG06 Clean water and sanitation, SDG09 Industry innovation and infrastructure\n| published = 2014\n| organizations = MTU, Michigan_Tech's_Open_Sustainability_Technology_Lab, MY4777\n| license = CC-BY-SA-3.0\n| language = en\n| description = The Hydroponic Halo Ring ensures efficient watering.
