Screw Threads, Holes, Bolts, Nuts, and Rods Library

thingiverse

This is not code, but rather a text file containing documentation and comments for a library of OpenSCAD modules. If you'd like, I can help you create an executable version of this library by translating the comments into working OpenSCAD code. However, please note that this would require significant work and may involve making assumptions about the intended behavior of certain functions. Here's a possible implementation of some of the functions mentioned in the documentation: ```scad // Phillips tip hole module PhillipsTip(width = 7, thickness = 0, straightdepth = 0, position = [0, 0, 0], rotation = [0, 0, 0]) { // Create a cylinder for the hole cylinder(h = width + thickness, d = diameter); // Add a straight section at the bottom of the hole translate([0, 0, -straightdepth]) cube([diameter, diameter, straightdepth]); } // Metric bolt module MetricBolt(diameter, length, tolerance = 0.4) { // Create a hexagonal base for the bolt hexagon(diameter); // Add threads to the top of the bolt thread_tpi(1.5 * diameter / M_PI, diameter); // Add a countersink at the top of the bolt countersink(diameter, tolerance); // Translate and rotate the bolt to its final position translate(position) rotate(rotation) linear_extrude(length) PhillipsTip(width = diameter, thickness = 0, straightdepth = 0); } // Metric nut module MetricNut(diameter, thickness = 0, tolerance = 0.4) { // Create a hexagonal base for the nut hexagon(diameter); // Add threads to the top of the nut thread_tpi(1.5 * diameter / M_PI, diameter); // Translate and rotate the nut to its final position translate([0, 0, thickness]) rotate(rotation) linear_extrude(height = thickness) PhillipsTip(width = diameter, thickness = 0, straightdepth = 0); } // Rod start module RodStart(diameter, height, thread_len = 0, thread_diam = 0, thread_pitch = 0) { // Create a cylinder for the rod cylinder(h = height + thread_len, d = diameter); // Add threads to the top of the rod if (thread_len > 0) thread_tpi(thread_pitch, thread_diam); } // Rod end module RodEnd(diameter, height, thread_len = 0, thread_diam = 0, thread_pitch = 0) { // Create a cylinder for the rod cylinder(h = height + thread_len, d = diameter); // Add threads to the bottom of the rod if (thread_len > 0) thread_tpi(thread_pitch, thread_diam); } // Thread pitch function thread_tpi(pitch, diameter) { return pitch / (diameter * M_PI); } // Countersink module countersink(diameter, tolerance) { // Create a countersink at the center of the bolt translate([0, 0, -tolerance]) sphere(d = diameter + tolerance); } ``` Please note that this is just one possible implementation and may not be exactly what you're looking for. Additionally, this code may need to be modified to fit your specific needs. Also, keep in mind that OpenSCAD has a lot of built-in functions that can simplify the process of creating these kinds of parts. For example, you could use `cylinder()` with the `d` parameter to create a cylinder directly, rather than using `hexagon()` and then translating it into a cylinder. I hope this helps!
