This is a 3D printed rear double cup holder for the 2015-2020 GMC Yukon and Sierra. It also works on the Chevy Suburban, Tahoe, and Silverado for the same years. It mounts to the backside of the center console giving access to the middle row but still accessible from the front row. This is made of ABS plastic with a textured finish coating. It can hold two cups and two pens. There is also a larger round hole to store a flashlight if desired. The inserts are removable to be able to accept large bottles like Hydroflasks, Yeti 36oz bottles, and Nalgene bottles.. It hooks onto the storage compartment on the backside of the center console. This comes with 3M adhesive to permanently attach it if desired. It also has 4 screw holes if you want to bolt it on. The hook by itself will also keep it attached to the console but it can slide a bit left to right and be kicked off by little kids with clumsy feet if you don’t use any adhesive or screws. If you simply use the hook for install then the install time is about 2 seconds. If you choose to use the provided adhesive then you add about 30 seconds to install.
