Do you need to draw a vertical line on the edge of the workpiece to be marked? Why not try this ruler stop block? I specifically designed and printed this ruler stop block, which perfectly fits my stainless steel ruler. At the same time, its structure is flexible enough to be compatible with rulers of various specifications. Whether it's woodworking or various handmade creative projects, this is a practical and convenient helper.

Unprinted parts:
