Adjustable Focusing Tools for Laser Engraver (80-485mm) Fiber/Hobby/CO2/UV/Galvo Lasers

This is a kit to construct multiple laser focusing tools for your laser engraver, fiber laser, hobby laser, co2 laser, or other laser, or other application that requires a specific distance to be set and repeatedly used. These focus sticks ensure your laser engravings come out crisp and in focus, with the perfect laser distance each time.

★ Setup once, lock in place, and have a precise distance reference wherever you need it ★

Especially helpful when engraving at multiple heights or with different lenses.

These carefully 3D-printed pieces feature sunk in screw holes and a secure groove for the M3 nuts to be held in. Screw holes are intentionally snug, ensuring your measurement setting does not shift over time.

Each tool in a kit comes with two pairs of M3x6mm screws/nuts to assemble it with.
