This is a 2 inch miniature wall spike trap. It has four components. Nonfunctioning gears are on the side of the base and a wall with holes. There is a slide with spikes that can be moved in and out relative to the front face with a stone wall. Also there is a nonfunctioning handle at the back as if this activates the sliding spikes or sliding rear door. I have also provided the face of the spike trap with and without holes so that you could set up a game with faces that are not traps and then the face with barely noticeable holes until the spikes emerge.
You can also face the spikes inward and have the characters enter from the door at the rear. Then close the rear door and they are trapped with spikes coming towards them. Your choice of victimization.
Also I haven't glued the front face to the body yet so when I took the picture it appears that the face doesn't line up with the body, but this is not the case. When I put them down I allowed the face to move and didn't catch it until after I took the pictures.
