Ốp cứng Samsung Galaxy A36 (Hard Case)

Put a lot of work into getting this a perfect snug fit.  Shouldn't interfere with any screen protectors, allows you to set phone flat on a surface too, eliminating camera bump. Screen is protected with a lip.  

Designed with PLA printing in mind, PETG might be a bit too flexible.  I printed at .12mm layer height.
Use inner/outer wall printing order for the overhangs, and unless you know you have really good bed adhesion I would recommend using an outer brim.  No supports.
