Better Somrig battery cover

I was fed up with the Somrig switch constantly falling out of the metallic holder and tracd the problem back to the magnets inside the lid. The magnets are more than strong enough to hold it on firmly, but are hindered by the lid design, which holds them too far from the metal holder.

This quick design aims to solve that problem while re-using the original magnets. Print with supports. There are some tolerances designed in to help with support removal, no cleanup of the surface should be needed.

Extract the magnets from the original lid, glue them in the new lid, snap the lid on. It doesn't have the rubber lip the original has, but if you're printing this, you probably don't remove the switch from the holder much.

I don't have a Rodret switch to test, but the lid looks close enough to fit. Please provide feedback.
