Here it is, my iPhone 6s case designed and printed by JONESIUM DESIGNS. I used the filament PCTPE by Taulman. Its a mixture between nylon and TPE. This results in a very very strong case that is also flexible. You can also dye them any color you want. I will write a short summary of the process from designing to printing shortly.
My PCTPE settings were as follows:
Hot End: 235
Heated Bed: 95
Print Speed: 50mm/s
