Since buckle sizes vary depending on the application, I made a fully parametric OpenSCAD design. There are several other buckle designs available, but none of them can be scaled easily; many of the designs found only provide STL files.\n\n== Bill of Materials ==\n\n# Filament (amount depends on size of buckle)\n# Design files (OpenSCAD and STL): [https://www.youmagine.com/designs/parametric-buckle | Youmagine Link]\n\n== Tools needed ==\n\n# [[Athena Build Overview|MOST Delta RepRap]] or similar RepRap 3-D printer\n\n== Skills and knowledge needed ==\n\n* Knowledge of OpenSCAD is needed to manipulate the parametric settings in order to customize the buckle (such as changing the buckle width in the code to match application).\n\n== Technical Specifications and Assembly Instructions ==\n\n# Print Settings\n## Male Buckle: 30% infill, 0.2mm layer height, 60mm/s print speed, print with prongs flat on bed. No support needed. Print at 210 degrees Celsius for PLA.\n## Female Buckle: 30% infill, 0.2mm layer height, 60mm/s print speed, print flat on bed. Support recommended for the female casing; use Cura's \"everywhere\" support feature. Print at 210 degrees Celsius for PLA.\n\n[[File:Buckle male print orientation.PNG|300px|left]]\n\n[[File:Buckle female print orientation.PNG|300px|center]]\n\n# Print Times (Varies on size of buckle)\n## Male Buckle: 23min\n## Female Buckle: 27min\n## Overall time: 50min\n# Assembly\n## Estimated time: ~5-15min. This time accounts for removing supporting structure inside the female component and restitching fabric through the clips.\n\n=== Common Problems and Solutions ===\n\n* The female buckle can be made without supports; however, this results in a buckle that is easily susceptible to wear and tear. Using Cura's \"Everywhere\" support feature makes the buckle more robust.\n* Make sure to take time to clear the female buckle of support material before trying to use it. Failure to do so will result in a hard to use buckle.\n\n== Cost savings ==\n\n* Cost estimate uses the base STL files on Youmagine. Varying buckle sizes can result in different costs and savings due to the parametric nature of the project.\n# Total cost: $0.46 (20 grams PLA)\n# Commercial Part: $0.82 - $6 + S&H [https://www.buckleguy.com/7315-7316-3-4-rock-lockster-plastic-side-release-buckle/?gclid=Cj0KEQiAperBBRDfuMf72sr56fIBEiQAPFXszTH8WvwJFAprRLFIz-q0qukZa3f4yJZZXPIUcj9S6CMaAiF78P8HAQ]\n# Minimum savings of $0.36 (43.9% savings)\n\n== References ==\n\n* Used as inspiration for design.<ref>web page: Thingiverse Male Strap Buckle Clip Available: [https://www.thingiverse.com/thing:1416 http://www.thingiverse.com/thing:1416]</ref>\n* Used as reference for OpenSCAD design.<ref>web page: Snap-fit Clips Available: https://www.appropedia.org/%22Backpack%22_Snap-fit_Clips</ref>\n\n<references />\n\n{{Page data\n| keywords = 3D printing, buckles, fastener, osat\n| sdg = SDG09 Industry innovation and infrastructure\n| published = 2016\n| organizations = Michigan_Tech's_Open_Sustainability_Technology_Lab, MY4777, MTU\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:OSAT]]\n[[Category:OSAT 3D-Printable Designs]]\n[[Category:3D printing]]"}
