By modeling a bucket with just its top and bottom diameters and its average thickness, it's easy to design a spigot with contours that fit well. This design is expected to fit a wide range of bucket sizes effectively. The main attachment is reasonably easy to print, and typical modification requires changing only 4 parameters in two files.\n\n== Bill of Materials ==\n\n# OpenSCAD & the files located at http://libre3d.com/category/655/Plumbing/listings/800/Parametric-Contoured-Spigot-for-5-gallon-buckets.html<ref>http://libre3d.com/category/655/Plumbing/listings/800/Parametric-Contoured-Spigot-for-5-gallon-buckets.html</ref>\n# Appropriate feedstock for printer - be aware that some plastics like PLA absorb water readily\n# Will likely require a gasket of some sort between outer section and bucket - 3.5cm gasket or flat rubber cut to size will probably be sufficient\n\n== Tools needed for fabrication ==\n\n# [[Delta Build Overview:MOST|MOST Delta RepRap]] or similar RepRap 3-D printer\n# Tools necessary to make 3.5cm hole in bucket\n\n== Skills and Knowledge Necessary ==\n\n* Need to know top and bottom outer diameters of bucket, average thickness of bucket, and desired height of spigot - scripts will do the rest, assuming no other changes to geometry\n* Useful site for bucket dimensions: <nowiki>http://fivegallonideas.com/5-gallon-bucket-dimensions/</nowiki><ref>http://fivegallonideas.com/5-gallon-bucket-dimensions/</ref>\n\n== Technical Specifications and Assembly Instructions ==\n\n* Like many interlocking parts, especially those with threads, this is sensitive to print quality - use 100% fill, a reasonable layer thickness, and printing speed\n* Expect total print times for the whole assembly between 3-5 hours - obviously dependent upon print parameters\n* Assembly time is negligible, expect drilling the bucket to take longer\n* Be sure to orient prints for slicing in a sane manner - flat ends down, etc.\n\n=== Gallery ===\n\n<gallery caption=\"Parts & Assembly\">\n\nFile:Twfuller_spigot_1.jpg\nFile:Twfuller_spigot_2.jpg\nFile:Twfuller_spigot_3.jpg\n\n</gallery>\n</center>\n\n=== Common Problems and Solutions ===\n\n* Previously mentioned sensitivity to print quality and likely need for a gasket\n* Stopcock is prone to ill fit, may be replaced with screw-based design in future\n\n== Cost savings ==\n\n* Typical mass-produced spigots for buckets retail for ~$2-5, though none seem to account for bucket contour and few are designed quite as heavy duty, and the cost of feedstock is furthermore quite low\n\n== References ==\n\n<references />\n\n{{Page data\n| keywords = 3D printing, bucket, faucet, nozzle, osat, spigot, tap, Plastic\n| sdg = SDG06 Clean water and sanitation\n| published = 2014\n| organizations = MTU, Michigan_Tech's_Open_Sustainability_Technology_Lab\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:Water use]]\n[[Category:OSAT 3D-Printable Designs]]\n[[Category:3D printing]]\n[[Category:Plastic]]"}
