Generic case and lid - improved

thingiverse

This enhances on davidmpye's universal case (box and lid) from http://www.thingiverse.com/thing:28608. The revisions provide enhanced dimensioning across a broader range of parameters. The lid should fit snugly over the box, and an option has been provided to add a mounting flange for additional stability. As with davidmpye's design, roundCornersCube.scad from http://www.thingiverse.com/thing:8812 serves as the basis for the standard box. nophead's polyhole.scad is utilized for creating the small holes that allow for versatile usage of various tools and objects. The Rev A files represent a refined application of openSCAD, enabling users to individually tailor more dimensions with precision and ease. For instance, the wall thickness, base thickness, and lid thickness can all be adjusted independently according to specific needs. A reference table detailing common hardware dimensions is also included in the source file for added convenience. The mesh overlap between elements has been fine-tuned to minimize visual imperfections known as "ghosting" that may appear in the render view when multiple components intersect or overlap. Additionally, echo outputs have been incorporated into the console output to provide real-time updates on key calculation results, enhancing user understanding and problem-solving capabilities. To facilitate ease of use and compatibility with openSCAD's standard library locations, the path to roundCornersCube and polyhole has been revised. This enhancement streamlines access to these necessary components without requiring additional adjustments. The provided revA STL file showcases a sample output for a box measuring 50mm in width, 70mm in depth, and 15mm in height with wall thickness set at 2.0mm. The lid mounting posts are designed specifically for use with a #4 screw, making assembly and disassembly of the device relatively straightforward. For those seeking more complex designs or greater flexibility, this package includes sample code snippets illustrating how to incorporate custom board mounting posts into the box bottom and create unique hole configurations within the sidewalls and lid. These sample codes are easily editable to suit various applications. The Rev A STL file included with this package is primarily a demonstration of its capabilities, not necessarily intended for actual practical use.
