OpenSCAD Heat-set Insert Standoff Stud modules

thingiverse

This is a collection of modules for <a href="https://openscad.org/">OpenSCAD</a> that will create different-sized standoff studs with holes for a heat-set insert to be placed into them. I have created modules for various sizes of standoff studs. I am still very new to OpenSCAD. While it has been around for many years, I first heard about it exactly one week ago. For the type of projects that I work on, and the way my brain works, this appears as though it will be much easier for me to design with as compared with the commercial product <a href= "https://www.autodesk.com/products/fusion-360">Fusion 360</a> that I started out with. Many of my designs are for cases to hold electronic projects, so I will need to create designs for holding circuit boards that have screw holes in a variety of places. To make installing, removing, and replacing parts easier, I like using these brass, heat-set, threaded inserts. Depending on the project, some times I need tiny little M2 screws and other times I may need a screw up to an M5. Each hole for an insert has an 8° tapered edge, to facilitate lining up each insert. The depth of each hole and the diameter of each stud varies based on what insert that is used. For this reason, I recreated several iterations of these standoff studs for the different sizes. Below are a list of the modules I've created. * M2.0 Short * M2.0 Long * M2.5 Short * M3.0 Short * M3.0 Long * M4 * M5 I may find a need later to create more sizes. If you open up the OpenSCAD file, you will see that I’m a bit verbose, but I explained how and why I did things the way I did. To call up one of the modules, you would use the following syntax: > m3_long_stud(x-axis, y-axis, height of stud, offset from surface); The following is an example of this syntax: > m3_long_stud(0,0,7.8,0); This places an M3 Long stud that is 7.8mm tall at 0,0,0. The values for each of these inserts were extrapolated from several different sources but mostly from <a href= "https://www.makertechstore.com">Maker Tech Store</a> and <a href= "https://www.mcmaster.com/heat-set-inserts/">McMaster-Carr</a>. Maker Tech Store provided better information on each of the inserts that they sell. Their only issue is they only sell some sizes. McMaster-Carr carries a larger variety but their information is a bit disjointed, often mixing imperial measurements with metric, like using a hole that is 0.199 inches for an M3 insert. Maker Tech Store explains it in details and provides an image to understand. <img alt="" height="500" src="https://we6bb.net/images/inserts.png" width="800">
