The file 'IKEA MARKUS Wheel Stopper 3D Printer Model' is (stl) file type, size is 17.8KB.
I use this wheel stopper to keep myself from pushing away from the desk while sim racing. Adding rubber pads to the bottom of the stopper is recommended to prevent scratching the floor and to improve stopping power. Two of these stoppers are enough to hold the chair in place.
