Sliding door stopper

A simple 2-side stopper for holes 32mm in diameter and 40mm in depth. The flat screw is meant to block the holes, originally made for cats' paws.The stopping screw is meant to block the door from fully hiding inside the slide.Scaling shouldn't be a problem as long as both nut and screws are scaled to the same ratio (to have matching thread).I would advise using some lubricant/oil to make the threads move freely.
