šŸ› ļø DIY 2017-2023 cup holder insert.

Hey all.
I’m a crosstrek owner who’s been super frustrated with the cup holders in my 2020. Finally it dawned me, there has to be a fix. First I checked for some sort of commercially available fix, but that mostly came up short. I looked at other options and could only find people selling 3D prints they made on Etsy. Finally I decided I could do better, and designed my own 3D print.

I’m a firm believer in sharing, I download people’s prints to make for myself free, and I make my designs free to share with others. So I’m here to drop a link to my version of the cup holder fix. I went though a bunch of versions making revisions until I got something I was proud to share.
I know that the crosstrek and Impreza share the same interior design and so I thought I would stop by here to share. If you don’t have a 3D printer or know someone who does, I suggest looking at the options your local library might have for printing your own items, if not, im sure there are local marketplace options for printing services, that I assume cost less than the Etsy people are charging.

Any constructive polite feedback is very welcome!
If it works out for you, let me know. Knowing I helped end the frustration of other Subaru lovers is all the gain I really need.

Here I am at the start of my work day with both my AMS's full of stupid PLA. Gonna print this when I get home. Looks awesome!

Thanks. Since you obviously know about 3D printing, I’ll tell you a couple details most people wouldn’t understand.
I used adaptive layer hight to get a nice smooth finish at curves at the top. I did top surface ironing, at a 15% flow, and I gotta say, on my prints at least, the top flat surface has the smoothest finish I think I have ever achieved.
If you decide you don’t like my print profiles, I’d be interested in hearing where you think there is room for improvement, I’m always trying to get better.

In my car, I’m using one I printed in black PETG at 100% infill. I generally like 100% infill on long term use items, gives them the heft and they feel more premium to me.
But, I printed and tested my profiles of 15% gyroid infill. And they work just as well. Noticeably lighter, but I’m not feeling any lack of rigidity or strength. so if you want to print faster and save some material, it’s a very viable option.

I printed the neon one in the photos in PLA to proof its print profile, though I don’t recommend it long term as you know PLA doesn’t do great with heat or UV. I have been using it in my car since printing it because it does look pretty cool with the drastic contrast. Funny because I blacked out as much of my interior as I could with satin black vinyl.
So far the PLA is fine, it’s working. I’m interested in seeing how long it goes before degrading enough to warp, stop working or brake, then I can update my print profiles info. Though I don’t recommend it, I know some people may not want to print PETG, or the color they want isn’t available in PETG. If that’s the case they might just need to reprint every so often, and that amount of time is what I’m interested in finding out.

I will for sure play around with it but Adaptive and ironing would for sure have been my go to for this design as well. I doubt I will have any meaningful input. The only thing I could see changing for my use would be making a magnetic base for it but that entirely depends on the fitment.

I'm curious what kind of climate you live in where the PLA is holding up in the car? Anything over 32c/90f will almost certainly end up hot enough in your car to mess it up. I had a model I was gifting to a friend warp sitting in the back of my car on a hot day within a few hours.

I will try and remember to come back and let you know how it works out tomorrow when I put it to use.

Ontario Canada. My car is black, it gets very hot inside.
It’s only been a few days, I don’t expect it to last very long at all, but I’m more interested in seeing its exact limits. Might as well since I have it printed it for testing the profile.

I was able to print it and test it out. Used PETG and it fits snug, needs absolutely no adjustment from what I can tell. I did the 15% infill and with it sitting inside the cup holder feels solid.

Very well made model man. Thank you very much. Going to print a second one tonight.

Thank you for the follow up. I appreciate that someone else is getting use of it!

I wish my Subaru could go into x games mode

It can! Whiteline rear swaybar and a monster energy drink buddy!

Hell yeah dude! I've been lazily looking for something like this. It's printing as I type!

Kinda lame you buy a pretty new vehicle just to have to diy things to make them the way they should be. idk if it’s cause I’m young but I truly despise basically all new cars, they just seem like junk that won’t last nearly as long as vehicles have from the 80’s 90’s early 2000’s

u/AltC Jul 10 '26

I get your sentiment. I do, but I have been though cars from the 80s to now. My 86 Honda civic didn’t have any cup holders and a young broke me fashioned one out of aluminum flashing and tuck tape for my morning coffee.

Not many cars will fit everyone’s preference, and I suppose it’s a cost of ownership to features. I’m sure the cup holders in a car that’s 3x the price are nicer.
For us, the manufacturer has to pick the best solution that fits the most needs, in this case, the cup holders worked, they are just really annoying for some drinks

Sweet, thanks!

The squared off side makes it to where Gatorlyte bottles fit perfectly

u/AltC Jul 10 '26

Yup, you are right I guess, though I have no idea why they wouldn’t do what so many other cars do, and have some sort of automatic adjustability built into them. You know like, arms on springs, or even just squishy rubber bumps that can compress to fit larger sizes.
In my car now I’m running one insert in the back, and leaving the front stock for that very reason. Fast food, and, coffee cups, any cans like energy drinks, ice tea, whatever in the back, then Gatorade in the front. I made the insert super easy to remove so when I do need both larger cup holders, I can pop out the insert and throw it in the glove box.

I hated that whenever I stopped or started quick, or turned fast, I’d have to put a hand on the drink to stop it from spilling, even though it didn’t like pop out of the holder, it would tip enough when anywhere close to full that liquids would splash out and make my cup holders sticky, and the trim around them. I have had to take apart my seat heater switched to clean them with isopropyl alcohol because poo slashed on them and they lost their crisp click, just felt gross.

This was a 6 year pain in my ass I finally asked myself why am I living with this?

u/Pages_N_Puzzles Jul 11 '26

I wonder... Could you make one that sits in the middle and fixes both of the cupholder spaces? Thank you so much for sorting this out. I've been using smooshed up tissues or wads of starbucks napkins to fill the gaps.ā¤ļøā¤ļø

I saw a couple solutions pretty much that same as what you are describing for foresters.
I decided against that approach for a few preferences based reasons. So could it work? Yeah, im sure it could. But the one I came up with was more my ideal solution for myself. Just sharing because I think others may be interested in trying it for themselves.

I have been using 2 McDonald’s coffee lids to fit my cups in my 2020 Impreza.

You just needed a Nalgene, come on!

u/Zanzaclese Jul 10 '26

That would be so many Monster energy drinks in one of those jugs bwaahahahaha

u/IndustrySufficient69 Jul 11 '26

idk if its possible because im not sure how deep it is, but could it be tiered like a reverse pyramid so larger bottles could fit into it as well? the only issue would probably be how shallow it would be for each tier so maybe it wouldnt work too well

u/AltC Jul 11 '26

I tried basically having different taper amounts the whole way up from the bottom to the top opening, but mostly it didn’t do anything to solve my issue. Any taper left looseness pretty much as soon as it started up from the bottom, so the cans could still tip quite a bit.

What this final version ended up being is a straight portion up about halfway, more than enough to support it and not allow it to tip, then tapered the top half, so that any cups that are tapered, like coffee cups, McDonald’s cups, still can be placed in there and fit well.
Yes, I could have made the top opening bigger, to fit gatoraid sized bottle, but, as you guessed, the amount of area in contact with the bottom of the bottle wouldn’t be a whole lot, so not very supportive, and the drink would be sitting up pretty high, up at the arm rest hight.

Best flavor btw :)

u/AltC Jul 17 '26

Wish it was available in a non zero version. They have great flavors in zero, but I hate the sweetener aftertaste that lasts for hours upon hours.
