A long time ago, I saw a big guy do it with clay, today I use 3D printing to copy it, the size of the inlay is 11*19*78, if it is less than this size, it can be used by direct printing, if it is larger than this size, a non-Boolean model can be found in the file, create a cube with the z-axis larger than the model for Boolean (if you need a graphic tutorial, you can comment in the comment area), Boolean pay attention to move the cube up 4mm to ensure that there is enough support at the bottom

The model has been printed and tested several times, and it is basically fine

！ Pay attention to printing, after all, it is a plastic product, it is no problem to work normally, it is risky to use it as a shell for a long time, and you should pay attention to safety when playing
