A simple box I used to make a UV cure box with switch. I used Keenan's hinges and clips. It is hard to snap closed and open at this size, but works fine not snapping it closed all the way. You will need a 300x300 bed or larger to print. I wanted something big enough to cure the biggest of prints on the Phrozen Sonic Mighty 4k. I wired a UV light strip to a switch and used it to cover all the inside of the box and cut a piece of plexiglass to place in the bottom to get an all around cure.
Print the bottom with supports for the power switch port. I used this power switch that snaps right into the port. https://smile.amazon.com/gp/product/B07QSBBL9Z/
