Hello everyone. This is my first post on TMC and I am happy to join the fun on here. I have been reading a lot of posts and enjoying my S 85. I have a 2013 S 85, seven passenger (w/ rear seats) and with the family all in the car I quickly realized that 6 people (2 adults and 4 kids) and 2 cup holders... well the math doesn't add up. So, I did what everyone would do... First I went to Tesla.com, then the forums and then Amazon. I found a few things, but nothing seemed to quite meet cost, function or quality that I was hoping for. So, I then did what I like to do in these situations... I designed my own custom, form-fitted one and 3D printed it. Well, this is the first iteration and I have been using this 3D printed prototype for weeks. I have to say that there are a couple of things I may change, but I do not miss having my coffee cup or water bottle jamming my elbow and I love the drop slots for my phones and miscellaneous stuff. This drop-in takes up about 10 inches of the yacht floor, secured by Velcro, still leaving room for a full size tissue box, sunglasses case and other miscellaneous items you may want to place there. I have been debating about next steps and wanted to hear some feedback from the forum on the design and if there is any interest in these types of alternative accessories or other custom designed ones. I have been debating about a rear seat cup holder option as well.
