Vacuum tray replacement for cutting lightweight materials

I’ll be curious to see if you get enough suction to make it work here. Those fans are rated to 1.95 mmH2O, the ones I use are 27.3 mmH2O, about 14x as much vacuum and about 2.5x the airflow.

That being said, if you seal it up it might well be plenty. Vacuum works on surface area, so if you’re cutting larger pieces I bet they’ll stay put.
