UPDATE: Uploaded a new version both .stl and .stp files. The V42 files added holes on the top and bottom of the case for the microphones and made a couple of minor adjustments to the placement of the relief features including a slightly larger microUSB relief.

NOTE: This model was prototyped in PLA plastic with a very low shrink rate. It is designed to work with this material. IF YOU PRINT IN ABS YOU MUST SCALE THE MODEL BY AT LEAST .5% SO THE FINAL MODEL WILL FIT!

Fits like a glove, prints like a dream, this is a basic case for your Galaxy S4 Smart Phone. If you have a nurbs editor like Rhino or solid modeler like Inventor or SolidWorks handy download the stp file to customize your own case.

Printed on a Replicator 2

Print settings are pretty basic, two loops, .25 max layer height (lower will fit the phone better), 4 floor layers, 4 roof layers, use your filament cooling fan if you have one. I printed it without support and everything worked great, but that is a matter of personal preference.
