This is a box lamp that I designed that uses three sliding parts. There is a base piece that the power box is stored in. There is a sliding piece that has a hole
...Show more for the wire and a pole to wrap the lights around. Finally, there is a box piece which covers the lights. I also included another sliding piece without the pole if you want to use different lights.
