Stopper which can be mounted on winch steel wires to indicate the resting position of the wire.

You can use up to four M3x25 set screws, but in most cases only two are more than enough. Best to use fuzzy skin on the inside.

Designed for wires of 16mm thickness. The stopper itself is 6cm in diameter and 2.5cm wide.

Printed with PETG and tested on the steel wire of the Rotzler TR 080/70 on a Fire truck. The stopper on the images is secured with only two M3 set screws but holds surprisingly well.

This is only a prototype, some issues still needs to be sorted out. The hole for securing the M3 screw nuts for example is to small to insert the nuts with bare hands, it needs to be pulled in with a longer screw first. The overhang on the base is quite steep too, this may need an improvement or proper supports.
