Parametric Rounded Corner Box with Optional Lid

thingiverse

I often need a custom enclosure for electronics projects, and the rounded-corner style I like is very difficult to create in Tinkercad. I found a few box generators here on Thingiverse, but nothing seemed to be complete. So, I decided to learn how to use Open SCAD to create a parametric generator for a customizable rounded corner enclosure with an optional companion lid. The result can be exported from OSCAD as an OBJ or STL, suitable for further modification and/or 3D printing. To use the generator, load the provided .SCAD file into OSCAD and press F5 - a box with a companion lid should appear in the preview window. The dimensions and other parameters are set with the line rounded_box(54,41,25,2,3,true,2,2,1); at the bottom of the file. This generates a 54x41x25mm hollow box with 2mm radius corners, 3mm thick walls, a 1x1mm ledge for the companion lid, and the lid itself. Change these parameters to suit your project and regenerate with F5. When satisfied, use F6 to render the view, and then export the result as an .OBJ or .STL file. Frank
