this is a clam-shell style enclosure that was created for the tutorial on Inhale3D.com. The article is the 2nd in a multi-part series of how to design electronics enclosures for 3D printing. http://www.inhale3d.com/2012/10/enclosures-3d-printings-killer-app-part-2-design-simple-enclosures/Printed on a LulzBot AO-100 3D printer. .4mm layer height, 3mm filament. STL file provided.Designed using ViaCAD 2D/3D CAD package. The .vc3 source file is available for download, however, since this was created as part of a tutorial there's a full video on the CAD techniques used to make this object on YouTube: http://youtu.be/sJBVKGX0N2Y so you can see how it's made.All the instructions for the design and print of this can be found here: http://www.inhale3d.com/2012/10/enclosures-3d-printings-killer-app-part-2-design-simple-enclosures/Future articles will go into more sophisticated electronics enclosure designs and corresponding parts files will be uploaded to Inhale3D on Thingiverse.
