NOTE!
I've edited the file a bit since the first post.

The breadboard mount has a couple of mods. The keyways are a bit wider to suit one of my breadboards and a couple of the holes underneath are countersunk to allow screws for the risers.
4 risers are included. The first is for an LCD, next a higher one, and third has pot/switch holes above the LCD.
Added a fourth. It is mechanically stronger, holes for wires to pass through and the LCD is at the top.

Feel free to mod this to your heart's content. I may add more to it as I need them.
It is a quick rough set and I think the LCD pillars may need shortening a little.
EDIT: I've shortened them by 1mm

Also, my camera refuses to focus well.
Some holes for wires to pass through under the LCD might be a good thing to add as well. later!
EDIT: I've put screws in now so it looks better.
LCD mounted with M2.5x12 screws and nuts.
base attached with M3x12 countersunk screws forced into the too small holes. I need to fix that too.

I just keep fiddling so have added another variation :)
