Male and Female Threads Generated With stl_threads

Human: Built using stl_threads and other stl_cmds. Printed on my Makerbot Replicator 2. Check out the full story in my blog post below. Instructions stl_cmd is a powerful set of command line tools for manipulating binary STL files. stl_threads can create screw threads based on the ISO metric thread standard with ease. Unlike OpenSCAD solutions that perform numerous slow CSG operations, stl_threads directly generates the triangles needed to represent the threads quickly and efficiently. Any resolution or configuration is instantly generated. This file was created using the following commands: stl_threads -D 8 -P 2 -h 20 -a 90 male.stl stl_threads -f -D 9 -P 2 -h 20 -a 90 female.stl stl_transform -tx 15 male.stl male_transformed.stl stl_merge -o threads.stl male_transformed.stl female.stl Get documentation for stl_threads here. stl_threads [ -f ] [ -D ] [ -P ] [ -a ] [ -h ] [ -s ] Creates an STL file with male or female screw threads according to the ISO metric screw thread standard. -f Creates female threads (defaults to male). -D - Changes the major diameter of the threads. -P - Changes the height of a single thread, or pitch as per the ISO metric standard. -h - Changes the total height of the threads. -a - Changes the thread angle in degrees. The standard and default is 60 degrees. For 3D printing this can cause issues as 60 degrees results in a 30 degree angle with the ground plane. Setting to 90 degrees results in a 45 degree angle with the ground plane. -s - Changes the resolution of the generated STL file. More segments yields finer resolution. is the number of segments to approximate a circle. Defaults to (every 5 degrees).
