I recently printed the wave lamp ( https://www.thingiverse.com/thing:774456 ) and wave lamp base ( https://www.thingiverse.com/thing:904653 ) but was unsatisfied with the open hole top when the two are put together. I created this cap To fill the hole on top and to attach all the pieces together. Fits snugly as is but could be glued as well if you are looking to create a finished piece. Print base colored or the color of the lamp if you would rather it blend in.
