My Daughter is come over tonight. I will have her, hopefully, post a couple of photos on the thread.
FWIW, I like @whart idea of the Hockey Pucks. You could get creative and start with a puck laying flat for a base.
Then two standing vertical
One flat
Two vertical
And so on until you reached the desired height.
For fine tuning you might have to double two horizontally for the base
Even tvad ideas were good. If PVC pipe, say 3/4" or even 1", were used for the riser, the base could be a no thread PVC floor flange. I’m sure there a top PVC fitting that could serve as a cradle support.. And the top cradle fitting could be made adjustable for different heights.
One thing about resting, supporting, from the floor it ain’t gonna give...
Edit:
The top cradle support could be a 1-1/2" Tee with a reduced sized leg. The top of the 1-1/2" tee would have half of it horizontal length cut away making a cradle to support the plug body or cable.
