I designed a case for the IPhone 5s/5c using Solidworks.
The this layout was chosen by me as I believed the combition of distinct curves created a layout thta was unusual and fascinating.
This case clips easily onto the telephone shielding the edge and the rear from scratches.
I designed it to be a print that was a quick and simple - set level down onto the print bed, so the file will print as it is - without any need for any additional measures or support materials.
This instance was printed using an Ultimaker 2.
I used white PLA - at a layer height of 0.2mm and print speed 50mm/s with great effects, as it's a quick print you could reduce the layer height farther or select slower print settings to create an instance of even higher quality.
