30AWG Wire Stripper from Up-cycled 3.5 inch Floppy Disc

thingiverse

A 30 AWG prototype wire stripper crafted from a repurposed 3.5" inch floppy disc, boasting an innovative design built around a floppy disc alloy hub featuring a strategically placed shear/cut edge. To create this unique tool: Gather discarded 3.5" floppy discs and carefully extract the alloy hubs. Measure the diameter of each hub to ensure accuracy in adjusting the Openscad script, allowing for a loose fit within the 3D printed part. Export the STL file from Openscad and proceed with printing the custom component. Initiate the construction process by making a precise cut on the alloy disc using tin snips, as depicted in the accompanying image. Permit the metal to deform without flattening it afterwards. Insert the disc into its designated position within the 3D printed part and secure it using an M4 screw with a length of 12mm and a matching nut. Fine-tune the shear cut by employing fine pliers, striving for optimal performance in wire stripping. Note that alternative positions are available for smaller gauge wire stripping. To effectively utilize this wire stripper, push the wire into the alloy's shear-cut opening and then pull it out, ensuring the direction of force does not cause the alloy to dislodge from the 3D part but instead remains securely attached. Notwithstanding its precision design, using this tool to strip small wires can be challenging due to the risk of shearing through them entirely. The accompanying Openscad script allows users to customize and refine their wire stripper according to specific needs.
