Parametric NEMA rack rails
thingiverse
The provided text outlines an OpenSCAD script for generating NEMA rack rail shapes according to user input. It was designed with 3D printing in mind, but also works for CNC machining. The rails can be customized for sizes from 1U to 3U and can be mounted on shelves or used as table-top enclosure corners. Longer rails (6U+) may exceed the capabilities of most 3D printers but can be machined out of bar stock or well-aligned angle brackets using a CNC. To use the script, edit the nema_rails.scad file to select desired size, top caps, bottom caps, mounting holes, and rails. Run the customized file through OpenSCAD, save the output, and beware of an error message if your rail height exceeds standard CupCake or Mendel bed sizes.
With this file you will be able to print Parametric NEMA rack rails with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Parametric NEMA rack rails.
