Please share ressources about the clamshell lock and hinge design.

Tolerances for button lock, angle draft, shape to get a working lock (depends on thickness probably), best living hinge profil with dimension....

or simply post link to references design guide, if you do have one, because I guess there is a lot of rules to follow depending on the product purpose.

As a starting point here is live scenario that I need to produced.

A clamshell design for a stainless steel mirror polish part. Such clamshell will be used to protect the part against stratches during the supply chain and need to be open and close several time and reuse for other part, once the first one arrived at the end of the supply chain.

Thanks for your help.
