Hello you all,

To answer your question what it is; it is the piece of a cable for an elevator which is over two wheels. The other parts are two straight tubes (cables) which can grow ore shrink and are attached to the lose ends of the model. (One attached to the elevator and the other one attached to a contaweight).

@ulillillia; thank you verry much for creating the model but as you can see in my drawing it has to have a diameter of 1.8 quants (it must be round not flat).
Still wondering how you made this, is it like I tried to do with a cylinder, extrude it, rotate it and move it into place? Please help me out here.

Regards,
Frits
