iPhone 4/4s Case basis for modification

thingiverse

This basic iPhone 4/4s case is ideal for customization purposes, as demonstrated in my Gear Case with Geneva Mechanism and Card Holder Case projects. The design boasts easy printability, durability, and a perfect fit. Key areas under the buttons and sliders have been removed to enhance usability, while a cutout around the headphone port allows for larger jacks without case removal. Furthermore, the edges of the case prevent screen contact when placed face down. The ledges holding the case onto the phone feature a bevel that facilitates print without support, ensuring ease in production as long as layer heights remain low enough to take advantage of this feature. A 1% size increase may be necessary due to potential shrinking during printing. To print this case, use 0.1 mm layer heights, no support, and single perimeters. The bevel on the ledges that hold the case onto the phone will only function effectively if layer heights are sufficiently low. You might consider scaling up the case by 1% to account for any potential shrinkage during printing.
