3d design "ear saver" for 3d printing (small medium and large sizes)

I'd like to have designed an ear saver. This should be very quick for an experienced 3d modeller, please be able to complete immediately. This will fit on the back of the head, to allow the loops of a mask to connect to this. There are many examples of these on thingiverse or other 3d printing sites. The item designed here will be 3d printed so please use relevant design principles. I will also want some text on the side (to be decided). I can send some example pictures. The arc will have hooks on the outside that loops would connect to. All 3d design ownership will transfer to me upon payment of the project. Please quote "earsaver" in your submission to show me you have read my details completely.
