Hello, there are different ways to do this. The most important to decide the way is the design. If the cover will be flat with an engraved design, maybe you could use different technique like laser, to engrave directly to a rubber part. If the design contains some 3d design with engraved parts, etc, then you could use 3d printing or silicone moulding if you need quantity. All the techniques are not very expensive. If you need more help let me know and we’ll see the best way to produce your idea.
