About this 3D model

Updated a 1.2mm thickness version, better print with PETG I found that the phone cases available on the website were too thick, bulky, and lacked bottom protection. Additionally, due to issues with the opening shape and interlayer adhesion of the material, they tend to crack easily after inserting the phone. Therefore, after a whole day of modifications, trials, and test prints, I have achieved the best version so far. I have made the following improvements: Reduced the overall thickness of the shell, from the original 2mm to 1.5mm for the borders and from 3.5mm to 1.5mm for the bottom. Changed the bottom design from an open style to a fully enclosed style, carefully adjusting the openings for the microphone/speaker and Type-C port. Fine-tuned the gap between the shell and the phone, slightly increasing the length to account for material shrinkage, achieving an easy insertion while maintaining a snug fit. Printing guidelines: Please use a layer height of 0.1mm, 3 walls thickness, and increase the number of bottom or top layers. Avoid using sparse infill. You can slightly increase the temperature by 5-10 degrees to enhance interlayer adhesion, especially when using matte/semi-matte materials. I have added three manually removable supports for the openings. You can also try printing a partial model to test the bridging effect. If satisfied, the supports can be removed.
