Volex ForgeParts › Hex Standoff Generator (STEP, STL)

Generate a hex standoff

A six-sided pillar that holds two panels apart. The hex form lets a spanner grip it, which is why standoffs are hex rather than round.

What it is used for

Dimensions that matter

Across flatsThe spanner size — measured flat to flat, not corner to corner.
LengthThe standoff distance.
BoreClearance or tapping size for the screw.
“Across flats” is the standard way to specify a hex — a 10 mm AF standoff measures about 11.5 mm across corners. State AF and the engine builds the hexagon to match.

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.
