Generate a quadcopter / drone X-frame
A one-piece X-frame: a central hub with four arms at 45°, each ending in a motor boss. Cut from carbon plate or 3D printed, it is the structural core of a quadcopter. Wheelbase is measured motor-centre to motor-centre diagonally — the industry convention.
What it is used for
- FPV and racing quadcopter builds
- Camera and cinematic drones
- Research and educational platforms
- Replacement frame plates
Dimensions that matter
| Wheelbase | Diagonal motor-to-motor distance — a 5-inch quad is typically 210–230 mm. |
| Arm width | Wider arms resist vibration and crashes. |
| Thickness | Carbon frames are typically 3–5 mm. |
What you get
A real solid model you can rotate and measure, plus downloadable STEP (machining and CAD), STL and 3MF (3D printing) and DXF (laser and waterjet) files. Optional built-in analysis covers stress (FEA), thermal, buckling, cost and manufacturability.
Before you see it, the built geometry is measured against the dimensions you stated, checked as a valid watertight solid, and — for assemblies — checked for interference. These are geometry and physics checks; they do not confirm the shape matches what you pictured, so review the 3D view or 2D drawing before relying on the part.
Previewing is free. Downloading is £2.99 per part, or unlimited on Pro (£29/month, £290/year).

Common questions
What file formats do I get?
STEP, STL, 3MF and DXF — the formats CNC shops, laser cutters and 3D printers accept.
Can I change the dimensions afterwards?
Yes. Edit the numbers directly, or describe the change in plain English. Every edit is rebuilt and re-checked.
Do I need CAD experience?
No. Describe the part and its sizes in millimetres.
Is it free to try?
Yes — describing a part and viewing the 3D preview costs nothing.
