[New / V4] Fix/replace clothing clip of Audio Technica Headphones ATH-ANC33IS

A spring-loaded cloth clip is originally made on the rear of the noise-cancelling controller of ATH-ANC33iS Active Noise-Cancelling In-Ear Headphones. It is, however, easy to break by its own spring. The noise-cancelling controller is sightly heavy, especially when a AAA battery is put inside. Therefore, I make this mould to reproduce the cloth clip for it.
