I recently discovered these inexpensive lab power supplies on Amazon, but they’re designed to be panel mounted so they aren’t enclosed. This is a simple box you can snap the power supply into to make it more convenient (and safer) to use.
Note: I designed this box for this particular power supply. While a lot of them on Amazon appear to be similar in size, your mileage may vary! Please double check your dimensions.
There are holes on the sides through which you can poke an allen wrench, etc. to pop the power supply out of the box if necessary.
