My wife complained that her cup holders were too difficult to get to when she was driving. They are underneath the floating shelf in the MG4. I printed these additional ones that fit in the sliding tray behind the original cup holders. They are a bit small (due to space) but they work for cans and (I think) Starbucks cups. Although, I'm not sure you'd get two in at the same time. Cans fit fine though. I could design an offset version of this with bigger holder but it would take up more of the space.

The sliding cover will still close up to the cup holders. The tray is mostly there to give the holder stability.

There two variants of this now, one with equal cup sizes and one with a big hole which should fit something like a Stanley cup (however, please note, I don't have one to test!!).  Note that the one with the big hole, the other hole is too small to fit a cup but it can be used for other things!

Each variant can be printed in one piece with supports or in two pieces with no supports.  Please make sure you have the correct version of the base for the split print as the support pegs are in different places depending on the position of the cup holes.
