I couldn't find a case that wasn't in TPU and my printer works better with PLA. I also wanted some more custom options. So, I completely redesigned this trying out multiple fastening methods and positions. Keeping this in 2 parts makes is so that it can be completely customizable on the top and bottom halves. This has the added benefit of being able to “mix & match” any alternant versions of the tops and bottoms that you print off later, keeping your design fresh.
