What I need is a back seat cup holder plug. My dog stands on the center console and would love to just cover them up completely so he does have to step in and out of the holes to move around.
Here is what I came up with as a solution in my truck. It's just a TPU (flexible 3d printed material) insert that holds the tabs in. Now it's not difficult to insert larger stainless steel cups, and doesn't run the risk of destroying a styrofoam cup. Here is a link to the 3d model https://makerworld.com/en/models/480267#profileId-391789. For anyone who doesn't have the capability to print their own, send me a message if you have any interest in purchasing a printed set.
FYI I have had thse installed in my truck for the better part of the month now and haven't had any issues yet.
