AURA No Math Focus Ruler

The easiest way to make sure items are within the allowable focus range for your AURA when the crumb tray is removed for engraving and scoring. No math, measurements, or calipers required.

Not for use with the Glowforge Performance Series. Please use the "No Math Focus Ruler"  instead.

As a reminder, do not put anything in your Glowforge printer that is not laser-compatible, even if you do not intend to cut or engrave it. This design is not meant to be printed on non Proofgrade material. If you are not using Proofgrade materials, please check with the material manufacturer to ensure the product can safely be used in your Glowforge for laser cutting. Use of controls, adjustments, or performance of procedures other than those included in the Glowforge manual(s) or with this design may result in harm to you or your machine. Printing on potentially non-laser compatible material or with the wrong settings can result in damage to your Glowforge. Additionally, any damage resulting from problems using potentially non-laser compatible material or manual settings is not covered by your warranty. This design is not meant to be used outside of the prescribed settings, description/uses of the design, and design instructions, and Glowforge is not responsible for any such deviation.
