ACME screw model.

[CADaver]

I have been looking for an accurate full ACME screw, but any so-called models I've seen on suppliers sites are just simple cylinders.
Does anyone know where I can find a full model or information on drawing one?
TIA

Hope that helps.

Farzad's LSP on the other forum site looks promising too!
