About this 3D model

Raise the legs of your wobbly furniture. Lazer cut the ones you need out of wood and glue them together to the height you need. Small feet on your existing furniture fit inside the holes to stop the raiser sliding around. Dead simple I know, but I just moved into a house with an uneven floor and this is a much prettier solution than the standard bit of folded cardboard. My shelves are now solid!
