so i am designing a modular wall. we are going to be able to move it and adjust it wherever we want. on the bottom of the wall module on each side there is going to be screws. each screw has its own mechanism connected and when i screw there is going to be a round pad extending which is going to touch the floor so that it won't move. the diameter of the pad is going to be 3-4 cm. there are going to be 4-6 pads. the material is going to be steel and it need to be able to attach on light gauge steel. the wall skeleton is going to be made out of light gauge steel and covered with plasterboard. i need you to design this mechanism. please ask me for more details.
