1. Combine the photos that need to be printed and cut them into a suitable ratio. The length-to-height ratio is about 3 to 1. 2. Enter the photo printing page on the printing website and set the photo size to 200mm. This size corresponds to the base and top cover I designed. and PCB.
3. Use slicing software to open the exported STL file, base and upper cover, output the G code and print the finished product! [{J1OZ$4[IQI5[`41{H6DULT.png]]
4. Install the debugged circuit board and battery, and install 18650 lithium battery, lead the touch wire to the upper cover and screw on a screw as a touch key. (You can color the inner layer of the photo)
5. Glue and complete
