I won't go into details since they were all taught by the same mentor. This was my first time experiencing JLCPCB's 3D printing and panel services. Initially, I wanted an acrylic panel, but the customer service representative called to tell me that acrylic couldn't be made with bulging, so I changed it to a thin-film panel. The buttons have a nice bulge. I

initially wanted a semi-transparent shell, but my printer couldn't handle transparent effects. So I used JLCPCB's 3D printing service to make a semi-transparent resin shell. The result is shown in the image:

The panel hadn't arrived yet, so I assembled it and checked the effect. I found some design flaws: the LCD screen edges weren't reinforced, and the four corner screws were too short to hold the motherboard in place, causing the motherboard to be uneven during assembly. So I modified the model and finally printed a white one using my own printer.

The shell model file is attached.

Below are the screenshots

On the software side, I developed using VS Code + EIDE on a Mac, and compilation was normal. However, the flashing process kept failing, even after trying several different linkers. Finally, I installed a Windows virtual machine and successfully flashed it via serial port. One more thing: I hope domestic chip manufacturers will also put more effort into software development and support cross-platform compatibility.
