Dupont Wire Bus Clip — Parametric

Dupont Wire Bus Clip — Parametric N-Pin Breadboard Cable Bundler

Keep your testboard wiring clean while prototyping.

This parametric clip bundles multiple Dupont jumper wires into a single flat bus — no more tangled cables shifting around your breadboard mid-session. Print one clip per signal group and your bench stays readable from power-on to teardown.

► What problem it solves

When prototyping with ESP32, STM32, Arduino or Raspberry Pi, Dupont wires fan out in all directions. A single accidental pull disconnects a pin and costs you 10 minutes of debugging. This clip holds your wire bundle rigid at the source — keeping all N wires parallel, seated, and strain-relieved.

► Parametric — customize before you print

Open the Customize tab and set:
- num_pins  is number  off row or collum you wan 
- wire_dia  : 2.54 mm for standard Dupont
 

No CAD software needed. Resize directly on MakerWorld and download your STL.

---

► Print settings

- Material     : PLA or PETG
- Layer height : 0.2 mm
- Infill       : 15% gyroid
- Supports     : NONE required
- Print time   : ~8 min per clip

---

► Use cases

- I2C bus  (SDA / SCL / GND / VCC)
- SPI bus  (MOSI / MISO / SCK / CS / GND)
- UART     (TX / RX / GND)
- Custom N-wire harness for any MCU project

---

► Compatibility

Fits standard 2.54 mm pitch Dupont connectors — the jumper wires that come with every Arduino/ESP32 starter kit. Works with both male-to-female and female-to-female wires.

---

► Files included

- Parametric Fusion 360 file (.f3d) — fully editable
- Pre-sliced STL for 5-pin (most common)

If this saved your sanity on a deadline build — drop a Boost. It helps more than you'd think.
