Wire Twister Attachment

thingiverse

I needed to craft a twisted pair using extremely fine wires (`AWG28` or `AWG30`) and I knew how frustrating it was to have a power tool chuck get a hold on those tiny wires.\r\n\r\nI did search Thingiverse first, but the [only design already available](https://www.thingiverse.com/thing:536925) didn't meet my needs, so I designed one myself.\r\n\r\nIt doesn't require any screw, bolt or nut, but you won't be able to twist the wires in their full length: something like `4 or 5 cm` of wires will remain untwisted because that's what anchors the wires to the attachment.\r\n\r\nUsage instructions should be pretty straightforward: insert the two wires into the inner holes then have them go through the outer holes and under the arc you just created. This _loose knot_ makes a tight connection between the screwdriver attachment and the wires.\r\n\r\nThe attachment has a `6 mm` shaft which can easily fit into the screwdriver clamping mechanism. From there, keep the two wires firmly from the loose end and spin the power tool until you reach the desired twist tightness.\r\n\r\nOnce I got there, I decided to take it further and create a `3`, `4` and `5` wires twister, which can be useful for wiring up sensors requiring more lines.\r\n\r\nIt should work with wires up to `AWG26`, but that really depends on the stiffness of the wires: remember this attachment, even if sturdy, is just made of plastic. In other words, a single-core `AWG28` is definitely tougher to twist than a multi-strand `AWG24`...\r\n\r\n## **UPDATE** (11 Jan 2020)\r\n\r\nI've added a `6` wires version along with the Fusion 360 project: please link back if you decide to customize the design.
