The is a rear double cup holder made for the 1996-2002 3rd Generation Toyota 4Runner. It is made of ABS plastic through the use of a 3D printer. It comes in the two factory colors of Tan and Gray. It can hold most beverage containers on the market. The inside diameter of the holes is 3″ so anything inside that diameter will fit. The flimsy factory rear cup holder will need to be removed first. There are two screws that hold the factory pull out cup holder in place. Once you pull it out you will be able to see and access them. Those 2 screws will not be reused. The new much stronger cup holder will come with 2 new longer screws. The cup holder should slide right into the hole left behind from the factory cup holder. You will need to apply force across the bottom to “click” the cup holder into place. Make SURE you here/feel the cup holder click into place. It has a locking tab underneath that will help secure it onto the console while you thread in the two screws. Remember that you are threading into plastic tabs and not metal. The screws can easily crack those tabs if you over tighten them. Get them snug and then stop turning. You can also use the 3M adhesive strip for added insurance but that is not a must.
