Wire Soldering Jig – Fast Print Clamp Holder with Spring, Anti-Slip Jaws & Fidget Function 3D Printed

This 3D Printed Wire Soldering Jig is a compact mechanical clamp designed to hold wires securely during soldering and other small electronics tasks. The 70 × 50 × 30mm size keeps it small enough for a desktop electronics workstation while providing a useful clamping area for wires and small components.

The design uses a spring-loaded mechanism to provide clamping force. The jaws are designed to close in alignment and feature an anti-slip surface to help keep the wire in position during work.

A major advantage of the design is its print-in-place construction. Apart from the spring, the main mechanism can be produced as a single 3D-printed assembly. After printing, the spring is installed from the underside through the dedicated slot.

The model is optimized for FDM printing characteristics and uses design techniques such as nesting and bridging. Its compact size also keeps material consumption relatively low, with approximately 30g of filament and around 1 hour of printing time, depending on printer settings.

The mechanism also provides a satisfying button and clicking action, making the jig usable as a small fidget-style desk accessory when not being used for electronics work. The audible click may vary or be less noticeable depending on the filament and print settings.

How to Use

1. Print the main jig using an appropriate FDM 3D printer.
2. Remove the printed part carefully from the print bed.
3. Check that the moving parts are free from excessive print residue.
4. Install the spring from the bottom of the jig.
5. Operate the buttons/clamp to check the jaw movement.
6. Place the wire between the jaws.
7. Release the mechanism so the jaws clamp the wire securely.
8. Perform the soldering or wiring operation while the wire is held in position.
   

Important Notes

• This is a 3D-printed mechanical jig, not a metal bench vise.
• The actual clamping force depends on the printed material, print settings, spring, and assembly.
• Do not place the plastic body directly against a hot soldering iron tip or molten solder.
• Avoid excessive force that could damage the printed mechanism or wire.
• Print time and filament consumption may vary according to printer, layer height, infill, wall settings, and slicer configuration.
• The clicking sound may vary or may not be noticeable depending on the filament used.
• Inspect the spring and moving parts before use.
• Product appearance may vary depending on filament color and printing parameters.
