Glass clamp

My new glass plate wasn't exact. So I made this so it wouldn't slide around. This is the "original" modified. My glass plate no longer slides as I put one of these in the lower right corner. Any corner would work. Sand the edges to fit your glass.

Update: I now just snip each lip off on all four now and they leave enough lip that no sanding is needed and the plate does not slide at all. Make an extra if you aren't sure how out of "true" your glass plate is.
