iPhone Duo and Galaxy Z Fold stand, open or folded

Props up a foldable phone on your desk so you can read it hands-free. The back leans at an angle, a lip along the front holds the phone in place, and a U-shaped cut in the back plate leaves room at the hinge. Change the case thickness and the lean to suit your phone.

Parts

  • stand · PLA · Upright on its base, as modelled; no supports

    155 x 100 x 89 mm at the default sliders, so it fits a 180 mm bed. The rear plate grows with the phone so the stand still needs at least 2 N at the phone's top edge to tip: about 184 mm deep for the Galaxy Z Fold6 and 197 mm for the Z Fold7, which need a 256 mm bed. PLA suits an indoor desk part; us

Notes
At the default sliders, 2 walls and 15% infill: about 98 g and about 2 h 16 min (136 min). Print upright on the flat base. The window's top is a 45° peak and the bed edges are chamfered, so no supports are needed. Extra walls or infill only add weight, which makes the stand harder to tip.

Hardware

  • USB-C charging lead (your own) · Optional, for charging the folded phone. The slot takes a plug overmould up to 24 mm long and 12.5 x 7 mm, on a lead up to 4 mm thick. Right-angle or very bulky plugs will not fit.

Assembly

  1. Pick your phone, case thickness, lean angle and cable side on the sliders, then print the stand upright on its base with no supports.
  2. For video: unfold the phone and stand its bottom edge in the cradle, leaning back on both shoulders. On the iPhone Duo the vertical hinge lines up with the centre notch (20 mm wide by default, adjustable from 14 to 30 mm). On a Galaxy Z Fold in landscape the backrest stops below the horizontal hinge
  3. For charging: from the window under the cradle, push the USB-C plug up through the slot in the cradle floor and plug it into the folded phone.
  4. Lower the folded phone into the cradle in portrait; the plug slides back down the slot.
  5. Lay the lead in the trough on the window floor. It turns on a 16 mm radius and leaves through the side window (left or right, as chosen).
  6. To take the phone off, lift it up along the backrest until it clears the 7 mm lip, then away.

Good to know

  • Phone sizes and weights: iPhone Duo from https://www.apple.com/iphone-duo/ (also listed at https://www.gsmarena.com/apple_iphone_duo_fold-13804.php); Galaxy Z Fold7 from https://www.samsung.com/global/galaxy/galaxy-z-fold7/specs/; Galaxy Z Fold6 from https://www.samsung.com/global/galaxy/galaxy-z-fo
  • The engine estimates that a horizontal push of 2.24 N at the very top edge of the phone tips the stand backwards at the default sliders, assuming 2 walls and 15% infill. Taps lower on the screen need more force. Hard pokes at the top edge can still rock it.
  • Charging works in folded portrait mode only. When the phone is open the USB-C port is off-centre, so it does not reach the slot.
  • The plug slot allows for the port sitting up to 20% of the folded thickness off-centre. The real port position was not measured, so check that your plug lines up.
  • The 14-30 mm hinge-relief notch is a clearance choice, not measured hinge geometry. Widen it if your case has a raised hinge cover.
  • The Galaxy Z Fold presets lengthen the base to about 184 mm (Fold6) and 197 mm (Fold7), so they need a bed larger than 180 mm.
  • At the 72° lean the phone still leans back only 3° if the stand is tipped 15° forward; lower angles hold more securely.
  • The fits, stability and strength were checked in the Loftsmith engine only. Nothing has been printed or tried with a real phone.
