I’ve had may folk ask if I hold the design copyright to this, so I’d just like to clarify that yes, I do. This is targeted squarely at companies: you’ll need to get in touch if you intend to copy my design to sell. For individuals reading this, making one for yourself (or a couple of friends) is fine of course, and encouraged! I just want to let companies know that they can’t steal my design for profit without prior arrangement… it’s happened before 😄
