Parametric Hinge

thingiverse

The text appears to be a design guide for creating 3D printed hinges using RepRap printers and materials like PLA or ABS. The guide provides detailed information on designing and printing hinges with specific parameters such as thread size, head diameter, fastener count, column count, margin, print settings, and support requirements. Here are the main points covered in the guide: **Design Parameters** * Fastener Thread: specify whether to support self-tapping screws or larger machine screws * Fastener Head Diameter: make this diameter 0.5mm to 1.0mm larger than the actual fastener head diameter * Fastener Count: number of fastener holes per leaf (total number will be "2 x Fastener Count") * Fastener Column Count: specify whether to arrange fastener holes in one or two columns * Fastener Margin: distance from the circumference of the fastener head to the edge of the leaf (values between 3mm and 5mm recommended) **Print Settings** * Printer Brand: RepRap * Printer Model: RepRap Kossel * Resolution: x = 0.3, y = 0.3, z = 0.15 * Infill: 66% or more recommended * Print Speed, Resolution, and Temperature: print slowly (4mm/s to 8mm/s), at a high resolution, with a temperature of 190°C for PLA **Support Requirements** * Supports are required to support the curved regions of the knuckle joint near the build plate * No support is required for the internals of the knuckle joint segments if reasonable component clearances (0.2mm to 0.3mm) are used **Post-Printing** * For component clearances less than 0.4, the knuckle joints can be tough to free up; a softening method using hot water is recommended * For simple hinges with 3 to 5 knuckle joints and a component clearance of 0.4mm or more, the hinge may move fairly freely straight off the build plate The guide also provides some general tips on how to print the hinges, such as printing slowly and at high resolution to get a smooth moving hinge with small component clearances. Overall, this guide appears to be comprehensive and well-written, providing detailed information for designers and makers who want to create 3D printed hinges using RepRap printers.
