This printable parallel block set (Sizes 1–5) is designed to provide reliable, repeatable spacing and support for setup, layout, and light machining operations. Each size is supplied as a matched pair, ensuring consistent height when supporting workpieces in a vise, drill press, or assembly fixture.

The blocks feature flat, square faces with chamfered edges to improve durability and ease of handling. Sized for efficient 3D printing and optimized for standard desktop printers, this set is ideal for students, hobbyists, and makers who need accurate setup tools without the cost of hardened steel parallels.

Designed for use with wood, plastics, and light-duty metal work, these parallel blocks are a practical addition to any workshop, maker space, or educational environment.
