I bought a cup holder center console and cut it up to make this. it's from autozone for 4.99 did a lot of trimming. Then epoxy glued it together and it works great. Regular cups,red bull,beer bottles and cans. It drops in and you can take it out if need to clean. I'm happy with the finished product.
Nice mod! This is particularly useful for those who are on tight budget when it comes to mods for their 4R. I wonder how long it took to do all the trimming required to fit it inside the 4R.
I pre ordered a set of 3D-printed cup holders by a fellow T4R member here and received them not too long ago. It's been awesome to me so far. I would have probably gone the same route with you and trimming if I had time but with my busy schedule, I opted to place myself on the list for 3D-printed cup holders. Only a little over a month wait but no regrets!
