This is a remix of the remix found here: https://www.thingiverse.com/thing:5691470

I needed a doubled ended screw clamp to hold a plate to a table, so the kids don't pull the plate off. The original one wasn't long enough for the plates and the screw wasn't long enough for our thin plates, so I modified it to work. I also added a lever to the screw to make it easier to unscrew.

I suggest printing 6+ walls for strength.
