A winder is a device that allows extremely precise control, setting up each movement in tiny increments for linear movements. It is controlled by a wheel that controls a gear connected to a linear rack that performs the sliding.

At the end of this device you have mounted a Rig arm to hold puppets or elements in place. The major objective of this tool is to maximize the precision and control of a movement controlling an axis at a time. They are often used to achieve complex movements or simplifying one axis displacements.

It’s ending tip connection is a 3,96 mm square shape that fits in a brass square tube also supplied (4,76mm Square tube connector), if you want spare material you can find it at the materials section. It also has a M3 screwded hole in the tip.
