DIY male chastity belt (work in progress)

It might not seem like much at the moment, but it’s still a work in progress. As you can tell, I’ve basically got a secure locking harness set up (the only weak point is the plastic zip tie – swapping that for chain would require two extra locks, which isn’t ideal). Still, I’m stuck on how to complete the setup. I’m not sure what material or method to use to block access to the cock itself and how everything should be attached. Ideally, I’d like it so the chastity part can either stay on or come off easily. Any thoughts or suggestions? Image Image
