Enter your phone's thickness measured over its case — 11 mm by default — pick the viewing angle and how high the ledge sits, and get a one-piece A-frame stand like the most-downloaded printed ones. The backrest is long enough to support the phone past its middle, a gap in the front lip leaves the charging port and the bottom of the screen free, and the cable leaves through an opening at the back that the plug passes through.
The real generator runs in your browser: set the parameters, then download STEP or STL. Nothing to install, no sign-up.
The first open downloads the CAD engine (about 20 MB).
Each parameter below rebuilds real geometry on every change — this is parametric CAD, not a scaled mesh.
| Parameter | Default | Range | What it does |
|---|---|---|---|
| HoldsDEVICE | Phone, portrait | Phone portrait / Phone landscape / Tablet landscape | Sizes the backrest: 163.3 mm for a large phone upright, 77.9 sideways, 179.5 for a tablet. |
| Phone thickness with caseTHICKNESS | 11 mm | 5 – 17 | Measure over the case: a phone in a MagSafe case is about 11, a rugged case up to 17. |
| Viewing angleANGLE | 60 ° | 45 – 75 | How far the phone leans back from the desk. |
| Phone rest heightREST_HEIGHT | 25 mm | 18 – 50 | Raise it so a charging plug fits under a portrait phone. |
| Stand widthWIDTH | 60 mm | 50 – 120 | Wider for tablets. |
| Charging cable slotCABLE | on | on / off | An opening at the back for the cable, big enough for the plug to pass. |
Every parameter can go in the page's link, so one link opens exactly the part you want. Example (For a phone in a thick case, a little more upright):https://www.forgent3d.com/en/generators/phone-stand-generator?THICKNESS=14&ANGLE=65&REST_HEIGHT=30
STEP AP214 in millimetres, exact B-rep — it opens directly in SolidWorks, Fusion, FreeCAD, Onshape or Inventor, and goes straight into a CNC quote form. STL for the slicer is one click too.

Press “AI edit” in the generator and say what to change — a keyway, holes, a different shape. The AI edits the part's model.py and it rebuilds in your browser, with undo. A few edits a day are free without signing in; to keep the result or go further, copy it into your models and continue with the AI agent.
Edit with AI →For bigger changes, several rounds, or a part you want to keep: copy it into your models (free account). The Forgent3D AI agent reads the model.py, edits it, rebuilds it and checks the result itself.
Copy and continue with the AI agent →That is the most common complaint about printed phone stands, and the "for thicker phones" versions of popular stands are downloaded more than the originals. Measure your phone over its case and enter that; the ledge adds 1 mm of clearance.
Keep the cable slot on and raise the rest height until your plug fits under the phone; bent plugs need less. The rear opening is larger than the USB-C plug keep-out Apple specifies (12.45 × 6.60 mm), so the plug passes through it, and the gap in the lip leaves the port and the bottom of the screen free for swiping.
Lay it on its side in the slicer, so the profile is on the bed: no supports, and the layers run along the bends. Stick four 8 mm silicone feet into the recesses underneath if it slides on your desk.
Open https://www.forgent3d.com/en/generators/phone-stand-generator?THICKNESS=12&REST_HEIGHT=35&WIDTH=80 — the ledge sits 35 mm above the desk so a USB-C plug fits under a portrait phone, a gap in the front lip leaves the port free, and the cable leaves through an opening at the back that the whole plug passes through. Set THICKNESS to your phone measured over its case.
Yes: https://www.forgent3d.com/en/generators/phone-stand-generator?DEVICE=Tablet%2C%20landscape&THICKNESS=16&WIDTH=100 — the backrest is sized for a tablet held landscape (179.5 mm, an 11-inch iPad's width) and the ledge takes 16 mm with the case. Stands of this shape are sold for tablets the same way, with a wider ledge.
Yes. Models you generate and the STL / STEP files you export are yours: print them, sell the prints, or use them in a product. No attribution to Forgent3D is required.
