Volex Labs / Forge / End cap generator — text to CAD.

End cap generator — text to CAD.

Describe the cap — tube outside or inside diameter, round or square section, push-in or over-cap fit, wall thickness and depth — and Volex Forge builds the cap to the fit you need and returns a manufacturable STEP, STL or DXF.

No measuring and re-measuring a tube, no CAD seat. The cap is sized to your tube and fit clearance and checked before download, so it slips on snugly.

Frequently asked

Push-in or over the tube?
Either — say push-in (internal) or over-cap (external) and Forge sizes the cap to the bore or the outside of the tube accordingly.
Round or square tube?
Both are supported, with the corner radius set to match extruded square tube if you give it.
What does an end cap cost?
Forge is free to try; individual parts are from £2.99. You only pay when you download a file you want.
Which format should I use?
STEP for CAD and CNC, STL for 3D printing, DXF for the 2D outline.
