You need to make an embosser, as in the attached photo. I have a sample I can provide. This is a machine for embossing letters on a tape designed for this purpose. It is used in creativity - scrapbooking. If you need technical drawings, we will provide everything. The alphabet on the wheel needs Russian, all this is already drawn in 3D. The machine is almost completely plastic, there are a couple of metal parts. Approximately 15 cm. Or you need to separately make a circle with the Russian alphabet and other symbols according to the statement of work. First, a test sample, then we are ready to order a batch of 100 pieces by agreement with the manufacturer.
