I recently was turned on to a gentleman by the name of Gregory Bednar in Canton, Ohio that does these great engraved custom call sign labels for a multitude of the HT’s and Mobile radios on the market. He makes these on a laser CNC machine using a material known as Lamicoid; a multi-layered plastic. I really appreciate stuff like this, as I have a CNC router for woodwork in my Garage woodshop. These labels are really cool and very reasonably priced considering time, material and labor cost and look great on your radio. You can check out his handy work and get them for your radios on his website: https://sites.google.com/view/kc8gl/.
The radios he makes labels for at the moment:
