Model Description: A tool designed for measuring and setting the gap of spark plugs, specifically for REM38E models and other 18mm massive electrode spark plugs.

Usage: This tool is essential for accurately adjusting the spark plug gap, which is critical for optimal engine performance.

Construction Features: The tool screws snugly onto the spark plug. Required hardware includes 3 M3 T-nuts and M3 screws (16mm, longer screws can be used). The gauge is designed to work with a 0.017 guitar string, which can be glued into the holder or annealed for a better fit.

Printing Recommendations: Ensure your printer is well-calibrated. Print the tool vertically with supports, with the string hole facing up. Suggested settings: 1.2mm walls, 20% infill, 0.1mm layer height, using PLA material.
