This project involves creating a 140mm steel plate jig, crafted from 3mm or 5mm plywood. 

The jig is designed to assist in precise engraving tasks, providing stability and accuracy during the engraving process. (I use the steel plates from Te.mu)

This project is suitable for both hobbyists and professionals looking to enhance their engraving capabilities, allowing you to fully engrave your plate with this jig. 

Just cut and assemble the jig components.
