It seems like whenever your speaker falls off the desk, or you drop your phone with the earplugs in, or yank on your audio headset by accident, the jack always takes the damage. Typically, when the audio jack breaks, people are forced to buy a whole new device. They simply don’t have the time and/or skills to install a new one, which requires soldering and analyzing schematics. This is a fully 3D-printable TRS audio jack with a unique design to maximize ease of use. It replaces all standard 3.5mm audio jacks.

To use it, simply cut off your old jack from the wire. Strip the end to separate the wire into 3 wires: Ground (black, silver, gold, or copper), Left Audio (blue), and Right Audio (red). If there are two ground wires, twist them together. Use sandpaper to wipe the insulation off the ends of the three wires. Next, loosen the screws on the 3D-printed jack. Insert the ground wire into the hole labeled G, left audio into hole labeled L, and right audio into hole labeled R. Tighten the screws to clamp the wires and you’re done! No soldering required! ( If necessary, cover any exposed wire with insulation tape and use hot glue for a more secure connection).

If your jack ever gets pulled out again, simply reinsert the wires and tighten the screws. You never need to replace the whole device again!

*Printing this model requires a 3D printer capable of printing with two different materials including conductive filament.*This is a prototype. I hope to test and perfect the design if I get the opportunity to use a 3D printer capable of two materials.*Soldering is not required but can be done if preferred.*Every part file is included, but the entire assembly can be printed as one piece except for the two screws.
