Ok, I'll add what I made for my display.
First pic is what the wall looked like before.
Made out of 1x4 oak ripped to 3", due to where I wanted to place it I stepped it out so it would go over the edge of the movie poster.
And because I didn't want to look at any wires, I took 3/8" oak dowels and cut a groove in the back, and attached them to the sides.
You can see my saber holder which I can add the link if that's ok to where I bought it, I believe it was another link the I'd found it on anyway.
Here's what it looks like on the wall.
And here's what it looks like all lit up.
I also drilled a hole in the base, one to hold the saber and another straight through to allow the sound.
And haers a quick one of my blade holder.
Hope you like.
