Box or table tray with lip and cover (Customizable/parametric with OpenSCAD)

thingiverse

It can be flipped to serve as a standard box or table tray. The primary tray.scad file is licensed under Public Domain Dedication terms, but if you're interested in roundedcube.scad, please keep me updated on your progress. When you open tray.scad, various variables are available for customization of the tray's features. As a beginner to 3D printing, I would adjust certain settings differently next time. Perhaps I would have chosen thicker walls and a slightly higher rim, but I opted for less filament usage. Consequently, you may need to fine-tune this setting, especially if you're still getting accustomed to print settings. If you're well-versed in the subject, you can likely print it as-is without any issues. The next time I print one, I'll upload a revised .scad file. If you've customized the tray.scad file, when you're ready to export for printing, set your $fs variable in roundedcube.scad to 0.01 to achieve smoother corners. This may prolong rendering time, but it's worth the wait when the customization is complete. The modules/functions in tray.scad to keep in mind are build_base() and build_top(). The latter is commented out in the file upload, so you'll only see the base initially. This allows you to comment one out, export, print, then swap the comments and print the other part.
