Wire Twister Attachment
Description
I needed to create a twisted pair using very thin wires (`AWG28` or `AWG30`) and if you ever had to do that you know how painstaking is to have a power tool chuck get a hold on those tiny wires. I did search Thingiverse first, but the [only design already available](https://www.thingiverse.com/thing:536925) didn't look fit for my need, hence I went for my own design. It doesn't use any screw, bolt or nut, but you will not 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. Usage instructions should be pretty straightforward: insert the two wires in 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. The attachment has a `6 mm` shaft which can easily get into the screwdriver clamping mechanism. From there just keep the two wires firmly from the lose-end and spin the power tool until you reach the desired twist tightness. Once I was there I decided to go one step further and create a `3`, `4` and `5` wires twister, which can be useful to wire up sensors requiring more lines. It 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`... ## **UPDATE** (11 Jan 2020) I've added a `6` wires version along with the Fusion 360 project: please link back if you decide to customize the design.
