The ideal solution would be a box that comes in two equal halves each

to cut/grind these myself if I can find suitable boxes.

Could you remove the innards from cheap water-resistant 13A sockets
and just use the outers - spring close lids and squidgy rubber
grommets

Make them out of perspex and use silicon to bond the sides together, then
paint whatever colour.
