Samsung Galaxy Grand Prime Flex Case

thingiverse

This is a custom Samsung Galaxy Grand Prime case designed for flexible filament. I discovered that PLA cases are prone to cracking if dropped from even moderate heights. Even high-temperature PLA, which I annealed for added strength, couldn't withstand the impact. I grew tired of breaking cases and decided to create this one myself. FILES: There are two files you'll need to print: Grand Prime Flex.stl and one of the back plates. The two back plate options include a blank plate (which you can customize with Tinkercad) or the NSD hexagon plate that I currently use. You should attach the plate to the back of the TPU case using glue (I used super glue). Initially, I considered making them interchangeable, but I opted for a simpler design. You can print this case without a back plate, but having two colors or materials is a nice feature. If there's enough interest, I might make it interchangeable in the future. PRINT ORIENTATION: Print the flex case with its back against the build plate and use supports (obviously) for the buttons and bottom. Many people dislike using supports, but this design was the simplest one that still accommodates a back plate. Print the plate as desired. MATERIALS: I use Sainsmart TPU, but other flexible materials will likely work great too. If you want to use PLA with a case, this won't work since the lip is too large and PLA doesn't flex well. However, for the plate, any material can be used (I personally prefer PLA).
