How to cover metal with a plastic casing?

[tirelessphoenix]

Hi, I want to cover this piece of metal (A) with a plastic cover (white line B) that fits but I am not sure how that is created...do I need 3D printing?Has to be like an encapsulating plastic box that fits, hiding the underlying metal thing seen in the picture A...so the results is a smooth plastic surface, hiding completely the metal underneath...Does anyone know how this is done?

Out of curiosity, what is that metal thing? How heavy is it?

Do you want the casing to completely cover it with some sort of closure mechanism? Or will one end be open for inserting & removing the metal object?

its about half a pound. I want completely cover , closing mechanism not needed. I want terminal closing. Does not need to open for inserting & removing the metal object.

Just how hard and durable does the coating have to be? Perhaps something like Plasti Dip (https://plastidip.com/applications/), intended for tool handles, might work in your application?

Powder coating.

For small items, I momentarily dip the hot metal into old photocopier or laser printer toner.
