This tool converts two standard multimeter probes into a pair of testing tweezers, letting you measure components and contacts with one hand.

Ideal for SMD parts, tight spaces, or situations where you need one hand free to stabilize the board.

Simply slide your probes into the two cylindrical holders — the spacing and tension keep them aligned so the tips meet accurately. The “tweezer” action gives you fine control while the probes stay electrically isolated.

✅ Features

One-hand use for testing SMD parts, pins, pads, wires

Fits most standard 4 mm probe bodies

Spring-free friction mechanism — no metal parts needed

Compact, durable, easy to carry

Printable without supports

✅ Recommended printing

Material: PETG or ABS (for slight flex), PLA works but is stiffer

Layer height: 0.15–0.2 mm

Infill: 40–100%

Orientation: print flat for strongest clamp arms

Supports: not required

✅ Use cases

SMD resistors, capacitors, diodes

Measuring continuity on small pads
