I designed this case for the IPhone 5s/5c using Solidworks.
I found a similar pattern using diamond shapes and circles and thought it could create and interesting look if I repeated the pattern all across the back of the phone case.
This worked out well, after reducing the size of the pattern you keep an interesting look while still covering the majority of the back to keep the phone protected.
The case clips easily onto the phone protecting the back and the edge from scratches!
I designed it to be a fast and easy print - placed flat down onto the print bed (so the file will print as it is - without the need for support material or any extra measures).
I printed this one using an Ultimaker 2 but it will work just as well using other printers.
I used white PLA - at a layer height of 0.2mm and print speed 50mm/s with good results, as it is a fast print you could reduce the layer height further or choose slower print settings to produce a case of even higher quality!
