Library for Unified National bolts and threads

cults3d

OpenSCAD library for American standard bolts and nuts with exact thread profiles. The library allows to generate STL for threads from UNC #1 to UNC 4" and from UNF #0 to UNF 1 1/2". They can be generated alone or as part of another design. The STL for UNC 1/4", UNC 3/8", UNF 1/4" and UNF 3/8" bolts and nuts are provided in thing files to show the results. Howto Sample OpenSCAD file to render a 1/4" bolt in UNC standard:    use <agentscad/unc-screw.scad>    use <agentscad/unc-thread.scad>    $fn=100;    uncBoltHexagonalThreaded( UNC1_4() ); Sample OpenSCAD file to render a 1/4" bolt in UNF standard:    use <agentscad/unf-screw.scad>    use <agentscad/unf-thread.scad>    $fn=100;    unfBoltHexagonalThreaded( UNF1_4() ); Documentation Detailed documentation available in the GitHub Wiki Prerequisites Installation details also available in the GitHub Wiki See also Metric libs (https://www.thingiverse.com/thing:3837034) BSW libs (https://www.thingiverse.com/thing:4395165)
