This full 10-pair printable parallel block set provides a complete range of heights for precision setup, layout, and support in machining, assembly, and educational applications. Each pair of blocks is matched for consistent height, making them ideal for supporting workpieces in vises, drill presses, and fixtures while maintaining square and parallel alignment.

The set spans a full range of heights from 0.125 in to 1.250 in, allowing flexible stacking and accurate positioning for both small and larger workpieces. Flat faces and chamfered edges improve durability and handling, while the uniform footprint ensures compatibility across all blocks. Designed for 3D printing, this set is optimized for desktop printers and works well with wood, plastics, and light-duty metals.

Perfect for hobbyists, makers, students, and light workshop use, this set is a practical and affordable alternative to steel parallels, providing reliable setup and repeatable results for a wide variety of projects.
