Samsung Galaxy Note 4 smartphone cases for flexible filament

For my smartphone Galaxy Note 4 i’ve already tried many cases to print and use. Pretty much everything that’s offered on thingiverse at designs, I’ve tried. So far, unfortunately, there was none created/designed especially for flexible filament like TPU or similar.
That’s why I created this design with the Fusion360 software. Since I am not yet a Fusion360 professional, it was also a very good training to familiarize myself with this very complex CAD tool.

After several hours I had created the first case and already printed. Looks very good and it fits very well, the flexible filament is ideal for such purposes as it is very good and easy to process (almost like PLA), but on the other hand has really just the flexbility needed for such purposes.

Below are some pictures of the design printed with TPU in different shades:

I have now published the design on thingiverse, it can be found under the following link:

In order to change the backside with logos, font, icons, smilies or similar, I created another design with fusion360, which has a cutout in the back. This section can then be provided with a separate inset separately created with fusion360, which then contains the respective logo or icon.

Here are some pictures of how it might look like when printed:

 

The grid structure is not implemented in the design but comes out by settings of the CURA Slicer (Zero Top- / Bottomlayer). In the infill pattern I’ve selected the setting QuarterCubic, resulting in a nice optical grid effect on the finished printed object:

This design is also published on thingiverse and can be found here:

The flexible TPU filament from sainsmart was easy to print with my delta 3D printer anycubic Kossel Linear Plus. The printing speed was set to low speed (20mm / s) to avoid filament jamming at the extruder.

Since the bottom edges of the case are rounded, it is recommended to set the option ‘Make Overhangs Printable’ in the section ‘Experimental’ in the Cura-Slicer. This slightly changes the geometry of Cura so that the overhangs in this area can be printed without support:

With this adjustment there shouldn’t be a problem to print the backside-edges:img BacksideFlexcase
