A functional PCB ruler made from FR4 fiberglass with lead-free ENIG (Electroless Nickel Immersion Gold) finish. Thirty centimeters on one edge, twelve inches on the other — with Ohm's Law reference, Raspberry Pi 4 GPIO pinout, and PCB trace width guide printed in gold directly on the board. This West3D exclusive version features the Voron Design, Salad Fork, and Micron logos alongside the West3D mark, all in gold ENIG on a black substrate.

Actually Useful — Not Just a Novelty

The references printed on this ruler are the ones you actually reach for while building. Ohm's Law triangle for quick V/I/R/P calculations. The full Raspberry Pi 4 GPIO pinout so you stop tabbing between browser windows during wiring. PCB trace width reference for anyone doing board work or verifying clearances. Metric on top, imperial on the bottom. All of it in gold on black, legible, and permanently on your bench.
