Laser cutter Magnetic Square GlowForge Compatible

Magnetic 90° Alignment Squares for Laser Crumb Tray (Glowforge Pro Compatible)

Designed specifically for laser users who want fast, repeatable alignment, this set of magnetic 90-degree alignment squares locks your material into position directly on the crumb tray — no more eyeballing or wasted test cuts.

These right-angle guides use embedded magnets to securely grip the metal crumb tray of the Glowforge Pro (and other laser cutters with steel trays), keeping your workpiece square and perfectly aligned for consistent results.

🔧 Features

• True 90° precision corners for accurate alignment
• Integrated magnet pockets for strong hold to crumb tray
• Low-profile design to avoid interfering with laser head movement
• Ideal for batch runs, engraving grids, and multi-pass jobs
• Optimized for PLA, PETG, or other rigid filaments

🎯 Perfect For

• Glowforge Pro users running repeat jobs
• Engraving on coasters, plaques, tiles, leather patches, etc.
• Keeping thin materials from shifting during airflow
• Fast setup without jigs or tape

Simple designs are sometimes best. I created this after not being able to find something to work with my glowforge pro. This will work with other laser cutters/engravers and is only 8.3mm tall

Simply snap the squares into position on the crumb tray, push your material into the corner, and you’re aligned. Move them anywhere on the tray for flexible positioning.

Note, this is designed to have a pause at layer 34 to allow you to insert 6 magnets. I included the magnets I used that I picked up at Hobby Lobby for $1.29 for 6. So, you will need two packs. 

I used some old gradient PLA I had lying around. I would recommend a bright color
