Plaque standoffs I attach these to the back of a plaque I print. This gives a little space between the wall and the plaque, as well as giving a place to attach a wire or string for hanging. I use Gloop to affix them. 4 gives the plaque stability but 3 would work too depending on the size of the plaque. 2 are 2mm shorter, these are for the top. Adjust if needed. Picture only shows 1 size.
