Looking for a 3d print file

is that an adapter holder for the door pocket?

Yes it's a holder that fits in your door compartment. It's also a rubber material to prevent vibration and holds the adapter securely. I use mine every day.

Check thingiverse or maker world etc

This entirely varies on which car it’s for, have you searched on printables or thingiverse?

Just search "Tesla adapter door holder" or something on your 3d repository of choice. Never bothered to find that exact design, but there's a lot of similar ones around. [This is the first one I found.](https://makerworld.com/en/models/188476-tesla-model-3-j1772-adapter-holder-for-door-cup-ho?from=search#profileId-212702)

I just leave mine in the center console. I don't think I've ever used it.

I’ve got to print one of those if I ever find my adapter

Glovebox for me.

Tiny cubby in the left of the trunk for me. Have used it fairly frequently in parking garages where you can self-park and charging is available.

I believe the Y door mounted one here is what I just printed in PETG-CF. Came out really nice.

you charge every day?

As you should

You’re supposed to leave the car plugged in as well. It says so when you check your battery health

Yes, it’s fantastic!

Loose in the door for me….my stash of folded napkins provides anti vibration

C’mon dude, just google “tesla 3d print adapter charger” or something like that and options show up right away, print in PETG tho, PLA will melt inside your car.

What color is your wrap ? Looks 🔥

Yeah lol that took no time or effort, people are so lazy these days haha

Just search it on printables or thingiverse. I'm sure one of those has it

Not mine, some random video. I dont even have a tesla. Someone i know does and was asking for me to print the door holder thing

Fits nicely and well organized.

This is great word of caution. Don’t get anything inside of it with it facing upish. I personally have mine in a sunglasses slip case that is padded and it cost me $5. Then like the others I keep it in the center console. Then when I use it I put the slip case on the dash so I do t forget it. Save me a few times.

Depends on the year of the car... Newer one are every day.

Tiny cubby in the left of the trunk for me too, along with a small harbor freight pelican case knock off with the adapter, a 3d printed adapter lock, and a 3rd party high speed adapter for CCS

So I've been thinking about that. I drive my lfp m3 about 50 miles/day, and I charge with a 110v outlet, every day. I lose a little each day, and I catch up on the weekends, especially in the winter. I just keep the charge limit at 100 because that's what it tells me to do. If I install a 240, it'll almost never go below 80%. Even though it's an lfp, that doesn't seem great for the battery health. But you're also supposed to plug it in every day... I haven't decided what I'm going to do here.

You need to charge LFP to full fairly regularly to help calibrate the BMS, but you still don’t want to leave it at a high state of charge for long periods of time. If you don’t need the range I would let it deplete some before charging back to 100%. I think I’ve heard once a week to 100% is plenty, and really more for calibration, not longevity of the battery.

I just put my adapter in the frunk. Rarely use it.

That's about what I've read too. I was thinking of putting the charge limit at 80, charging every night so I don't get out of the habit of plugging it in and forgetting, and then just on a weekend or something putting it all the way to 100.

After all these comments, I'm still not sure what this is for? I mean, I see it's for a j1772 adapter, but adapter to what? There's nothing that fits in the door?

What is that used for?

[removed]

what is it ?

It fits in the door pocket and holds your j1772 adapter

An adapter to what?

So you can use a j1772 plug to charge your Tesla.

Yeah but an adapter to what?

? It just holds it so it's not rolling around on the floor. You pull it out of this triangle thing when you want to charge

J1772 is the round type 1 connector, so this is to hold the small adapter from type 1 to type 2 https://en.m.wikipedia.org/wiki/SAE_J1772 Here you can see the 3 most common connectors https://en.m.wikipedia.org/wiki/File:Tesla-type-1-inlet-tesla02-outlet-iec-type-2-outlet-background-blur.jpg

Ooh okay. And this is something that's used in the US? I haven't seen them here in Europe at all, so I thought it was maybe an adapter to 110 dc or something (the 220 adapter is waaay to big to fit in the door, but maybe 110 isn't).

Correct, it's a US standard. The standard supports both 110v and 240v. The Chevrolet Volt and Nissan Leaf used it. Nissan changed the plug to the NACS standard on the 2025 version for the US model, in the EU it still has the Type 2 plug. NACS has taken over as the standard plug for all EVs in the US. In EU they mainly use Type 2.

As a former Tesla Service Advisor I can confirm you want to fully charge LFP battery equipped models to 100% at minimum once a week for long term battery health. Honestly, with the LFP packs it's as simple as just leaving it at 100% and forgetting about it. Bonus fact: you can supercharge to your hearts content, those packs love it

Doesn't leaving it at high states of charge still degrade the battery? I've always read that charging it to full is just because of the voltage curve to make sure the BMS is calibrated.

The LFP cells behave a little different compared to most other ones. All the normal Li-Ion cells Tesla uses for instance, the recommendation is to leave the limit at 80% because charging to full is more detrimental to the pack health as a whole. On the LFP batteries it doesn't have this effect but leaving them at a lower state for more time DOES cause issues hence the recommendation to charge to 100% at minimum once per week and generally just recommending to leave the limit at 100%. That and the cells doing really well during DC charging events (supercharging) are why they were a favorite amongst the folks at my service center.

So what do you think about the pack never getting below 90%? If I charge every day and leave the limit at 100 it might never go below 90.

In that situation I'd probably just let it go a couple of days between charges depending on how long it'd take me to charge back up.

I've had issues with petg softening in my car too so print in abs or asa if your printer is capable

Im in Texas heat, let’s see how it goes, its been 3 weeks so far with a petg thing inside.

Do people use these adapters often? I have always had mine in the sub trunk and have never used an adapter in the 6+ years and 2 models that I've owned. I keep the mobile charger and various plugs in the sub trunk and only keep the nema 1450, 5-15 (normal 120v) for road trips just in case.

If you ever charge at a ChargePoint public charger or at work you need one.

Just throw it in the back side pocket. And leave some space for your door.
