A small Micro-Fit 3.0 connector kit for 4-circuit wire-to-wire or wire-to-board harness work. This Molex kit pairs dual-row 4-circuit housings with matching male and female crimp terminals, useful for compact 3D-printer electronics, toolhead wiring, and serviceable harnesses.

Why Micro-Fit 3.0
- 3.00 mm pitch keeps harness connectors compact without dropping to tiny JST-class contacts.
- Molex Micro-Fit is designed for power and signal interconnects; the family supports up to 10.5 A when the correct terminals, wire gauge, and derating are used.
- Positive-latching housings make it a better choice than loose Dupont-style connectors for printer wiring that gets moved or serviced.
