I didn't have any screws or glue on hand for this one, so I decided to make one that didn't use any.

Assembly:

All parts slide together, no glue or screws required. Part 1 requires some force to slide to Part 2, I was able to do it by hand with relative ease. Parts 2 and 3 slide freely, but the weight of the wire holds it in place fine.

Printing: 

Only part 2 requires supports, as shown in the slicer image. I found regular supports to work best, but my final print used tree supports and with a very small amount of clean up with a box cutter was good to go.
