Overview
This is a fully customizable contact jig designed for DuPont-style connectors, perfect for hobbyists, makers, and electronics enthusiasts. Whether you need a 1x6, 2x8, or any other pin layout, this jig adapts to your project with ease. It’s a versatile tool for crimping, inserting, or testing DuPont pins and cables, featuring a random mix of contact slots and needle cylinders for unique wiring setups.
Key Features
- Configurable Layout: Use the included OpenSCAD file to set any number of rows and pins per row—tailor it to your exact needs!
- Robust Design: Thick base (12 mm), large chamfers on slots (2 mm), and tall needles (25 mm) ensure durability and ease of use.
How to Use It
- Customize & Print: Open the OpenSCAD file and adjust num_rows, pins_per_row, active_pins, and active_needles to your desired layout. Export and print with a strong filament (e.g., PLA, PETG) at 0.2 mm layer height—no supports needed.
- Insert DuPont Pins: The top side is the insertion side. Push DuPont pins into the chamfered slots as defined by your configuration. Pin holes align with the jig’s needles.
- Crimp Cables: Attach wires to the DuPont pins. Needle cylinders (placed per your design) can guide or test connections.
- Remove Cables: Pull the cables out from the insertion side as needed.
Customization
- OpenSCAD Power: Modify row count, pin count, and slot/needle patterns in the script. Adjust dimensions or other parameters to fit your project.
Applications
- Prototyping custom DuPont connectors for Arduino, Raspberry Pi, or any electronics project.
- Testing pin configurations with configurable needle placements.
- Managing complex or unique wiring setups with ease.
