Stand for holding sign or menu etc.

I made this stand for holding my business advertising sign, but it could be used to hold any thin card or laminated paper sign.

There are 3 versions available:
Version 1 has a 1.5mm gab and a heavier base, so it will hold a heavier sign.
Version 2 has a .5mm gap and will hold 100gsm laminated paper snugly.
Version 3 has a .4mm gap and will hold 80gsm laminated paper (as per the example image) snugly.
