I hate the stock cupholder. I'm sure you understand. Maybe the later ones are better.

I decided to design and print a modular 3d-printable replacement. I went through many iterations before I had a good fit. The new one completely replaces the stock one with a large bin, which can either be used as-is for a catch-all (much more capacity than the stock setup), or receive one or two modular inserts. There are indexing keys to keep the inserts in place, even if one is removed. Each insert was customized for my most used equipment. In my case, I made two modules. I tried to make the whole thing fit nicely into the area, keeping the crowned shape of the console, and the fit ended up very nice. The cool thing is if I suddenly decide to start drinking out of nalgenes, or giant 7-11 soda cubs, or any other size container, I can print a new insert that fits the container perfectly.

Left Module:
1) Bottle holder that exactly fits a Kleen Kanteen, the bottle favored by our family
2) Angled slot for my phone X in case, include charge cable at bottom. Can just push phone into slot, and the charge cable plugs right in.
3) Exact fit holder for our LED rechargable flashlight
4) Slot for 1 micro-usb charge cable
5) Three slots for apple lightening charge cables. One slot is at bottom of phone slot. I only use two of them.
6) If no flashlight in place, there is a slot for a second phone, or can be used for my wallet.

Right Module:
A) Bottle holder that exactly fits our thermos we use in the winter
B) Concentric to that, and above, another bottle holder. This one is sized to fit most bycicle style bottles. Fits our Kleen Kanteen too, but with a little wobble.
C) Small catchall-bin for coins, set of keys, gum, etc.

I routed three charging cables from a 3-port usb charger I wired in under the console into the shell. There is a slot (not pictured) for routing the cables. Obviously, this is optional.

These cables are routed into a channel in the bottom of the left insert.

The charging cables wires can be pulled up and plugged into devices that need charging. I'm working on improving how smoothly and easily these pull out, and push back down.

Here it is loaded up.

Showing off the contour (asymmetrical! Thanks toyota!) which makes it blend into the stock console pretty well.

Let me know what you think, or if you have improvement ideas! It has been waaaay too much work for a cupholder, but I'm really pleased with how it worked out. We went for a 3-day camping trip, and there weren't bottles and charging devices sloshing all over the place!
 
I like it. Designing in a 3D environment is not easy . Well done.
 
That looks great. Well thought out.
 
Thanks! If anyone would like to print out their own, PM me, and I can share the file with you.
 
Hey I know I had some commentary on your key BUT, this is really cool, and I think its a product that has a legit market....I saw this and Immediately said I would buy one. Some people have made cup holder inserts but the idea of replacing the entire unit is great. I wish I had access to a 3D printer, or I would take you up on that offer for the file.
 
Very nice! The fit is great and the space is actually usable 👍
 
@Ohthetrees what model Kleen Kanteen does it fit? Any idea how close this is to a standard 1 liter Nalgene (3.6 inch diameter)? Would you consider making and selling this? I have no access to the 3D printer.
 
nice! how long would this take to print? I have a buddy who has a 3d printer...does it use a lot of supply?
 
Thanks for the kind words folks. Several people have PM'd me asking whether I'd print and sell one to them. Let me go through some of the considerations, and if people are still interested, I'll consider it.

This thing would be expensive
I thought about selling this after I printed mine, but I think it is just going to be too expensive for most people, and I don't want people getting mad at me for what is basically a hobby. I had enough of that in my key-fob thread.
Why would it be so expensive?
1) It takes 31 hours to print a shell and two inserts, tying up my printer from my other projects, and putting wear on the machine.
2) It takes several hands on operations because I can't print all in one go, takes 2 print jobs. So My labor basically.
3) It consumes roughly $25 in filament alone. Plus my electricity, other consumables like nozzles, print-beds, etc.
4) Most people would want their own bottle sizes, and probably some customizations, so it would take hands on computer time for each print.
5) I don't want to sound like an a-hole, but I make good enough money in my "real" job, that I'd really only want to print and sell these if I could make it worth my while.

I just priced the print alone at 3D hubs, and they would charge $175 to print it. If I matched that, would people be interested? I kinda doubt it, but who knows.


August in Seattle is not August in Arizona
In theory, PETG should be able to withstand car temps, but I'd want to find someone who lived in a hot climate to test it for me before I started selling it. It would suck to start getting complaints about melted cupholders. If the PETG melts, I'd have to print in ABS, which is harder to work with, and smells bad during printing.

Would it fit your truck?
This thing fits my console like a glove, quite tight, which is how I want it. But the fit and finish of the center console is a little rough, and I worry that it wouldn't fit other's trucks as well as mine, or maybe not at all. I might be tempted to sell to others with slightly looser tolerances to make sure it fits everyone's truck.

Cable Routing
I'd call the charge cable routing "experimental". I'm working on ideas to make the cables pull out and push in easily, but at the moment it is too janky to really sell as a final product. So I'd either sell without the cable holes, or with understanding that that feature may not meet expectations.

More development
It wouldn't be too hard to print in different colors. I could even add inlays with logos or text in contrasting colors. See my key fob thread for examples. Cedar's key fob build thread
I thought of developing a few "standard" inserts that fit common sized bottles and cups, I could also make a "one piece" version for those who don't need the modularity of the inserts. But I'm not really motivated, because I'm happy with my setup now, and unless people surprise me with how much they'd be willing to pay for a cup-holder, it isn't worth my time to develop.

In the mean time, for those of you who would like to take a crack at printing their own, PM me, and I'll send you a file.

Mine is the 27oz. I think the diameter of most of their bottles is the same. My opening is 73.25mm. The right side "bycicle bottle" opening is 76.75mm. A nalgene is quite a bit bigger at 91.5mm, and it wouldn't leave much room for the other features on my inserts. It would have to more like my right insert than my left insert.
 
There has been a couple of recent messages about this project, so I thought I'd do a little update.

Overall, it is working great! The original black PETG print melted on a particularly hot sunny day. I reprinted in white PETG, and it has been going strong through some hot CA, AZ, and Mexican summer conditions. If I had to do it again, I'd probably try printing in ASA, or even Polycarbonate, for better heat resistance, but the white PETG is holding up fine, so I'm not in a rush.

The retractable wire routes for charge cables both work and don't work. They are not easy-in easy-out enough that I stuff them back down into the slots each time I use them. They is just too much friction. However, it does work well enough that I stuff them back down when I'm cleaning the truck, or when I want it to look tidy. Even so, it is convenient to be able to charge a couple of phones right from the cupholder, without wires running from the dash.

I've attached a link to a zip archive of step, stl, and 3mf files. If you want to modify for your own purposes, I'd use the step file as the starting place.

Good luck, and have fun.
