Have you thought of custom hangers for clothing made from wood? (Think of the hanger as adverstising. Could just be a tag on an inexpensive wire hanger attached with string or made of leather to go over the hook?).
Key chain tags (again as advertising).
Custom Product displays? ( saw a pegboard design in the forum today).
Perhaps you are thinking just about your product line and not so much about auxiliary uses for a laser cutter?
Offering a customization service is also a possibility. Custom name tags are easy to do in a few minutes with a graphics program and quick to engrave in a jig if precut. Putting a first name tag on a purse. Makes the item more personal.
Amazon sells blank anodized aluminum dog tags.
Quick to engrave. Easy to attach with ball chain (also available on Amazon) to a purse.
