3D printing a stand, dock or case for iPhone Duo

iPhone Duo went on sale on 23 October 2026, so most stand and case files out there were made for other phones. Here are the measurements to check a file against, the settings that make a print last, and how to make one of your own.

From Apple’s published specifications. Measure your own phone, with its case on, before you print anything that has to fit snugly.

Will a stand for my old iPhone fit?

Probably not. Closed, iPhone Duo is 11.3 mm thick, about 2.5 mm more than an iPhone 18 Pro Max, so slots made for ordinary iPhones are too narrow. It’s also much shorter and wider.

Stands that hold the phone against a back rest with a ledge at the bottom, and MagSafe stands, are the most likely to work. Anything with a snug slot needs a new design.

Fit tips

Slot width

Make it 11.3 mm plus 0.5–1 mm of clearance, or your case’s thickness plus the same.

Camera bump

Leave a 5 mm recess, or the phone will rock on a flat cradle.

Open on a stand

Open, the phone is 164.6 mm wide and only 5.2 mm thick. A front lip about 3 mm tall holds it without covering much of the screen.

Weight

At 254 g it’s heavier than any other iPhone, so give the stand a wide base, or a pocket for a few coins or nuts to weigh it down.

Cable

If you want to charge on the stand, leave a channel for the USB-C cable.

Hinge

Don’t clamp across the hinge. Cases for folding phones are usually two pieces, one for each half.

Print settings that last

Car mountPETG or ASA (PLA softens in a hot car)4 walls, 30–40% infill
Case or bumperTPU 95A2–3 walls, print slowly

Lay stands on their side on the bed when you can, so the weight of the phone presses along the layers instead of pulling them apart.

Where to find iPhone Duo files

Search MakerWorld, Printables, Thingiverse and Cults for “iPhone Duo”.

Designs made before launch used leaked or guessed sizes. Check a file’s measurements against the table above, and look for photos from people who have printed it for a real iPhone Duo.

For general designs, browse the free models on Remeshy.

Make a stand nobody else has

Remeshy turns a description or a photo into a printable model, so you can have a stand that’s actually yours: a dragon holding your phone, your dog, a tiny version of your desk.

  1. Describe it or show it

    Type something like “a cat sitting next to a phone stand”, or use a photo of a stand you like.

  2. Check the preview

    You see a preview of the model first, free. Try again until it looks right.

  3. Create and export

    Tap Yes, Create 3D Model, then export the STL.

  4. Size the slot

    Scale the model in your slicer so the slot is 12–13 mm wide, and test-print just the slot before printing the whole stand.

AI models are great for stands with character, but they aren’t measured to the millimetre. For a precise dock, use the measurements above in a CAD app.

A stand made in Remeshy

This adjustable stand was made in Remeshy from a photo and printed by a Remeshy user. It was made for ordinary phones, so check its slot against the measurements above before printing one for iPhone Duo.

Questions people ask

What size is iPhone Duo for a stand?

Closed it’s 117.8 × 84.1 × 11.3 mm and open it’s 117.8 × 164.6 × 5.2 mm, with the camera bump adding about 4–5 mm. Allow 0.5–1 mm of clearance, more if you use a case.

Will an iPhone 18 stand fit iPhone Duo?

Usually not. Closed, iPhone Duo is about 2.5 mm thicker than an iPhone 18 Pro Max and a very different shape. Back-rest stands with a ledge, and MagSafe stands, have the best chance.

Can I download a 3D model of iPhone Duo?

Printable iPhone Duo models are already on sites like MakerWorld and Cults, mostly for display or for testing case fits. Check one against Apple’s measurements before you design a case around it.

Can I 3D print an iPhone Duo case?

Yes, in TPU. Make it in two parts, one for each half, so the hinge can move freely, and test-print a corner before printing the whole case.

Does MagSafe work through a 3D printed case?

Usually, as long as the back is thin. Keep it to about 1.5 mm; thicker backs weaken the magnetic hold.

What’s the best filament for an iPhone Duo car mount?

PETG or ASA. PLA can soften and sag in a car on a hot day.
