K40 Laser Cut Air Assist (8mm O.D. hose with Needle)

thingiverse

Remixed Avernois K40 air assist.svg to fit my current setup. Similar to his design, I redesigned the armatures to accommodate 8mm OD tubing and a bike pump needle for better airflow focus on material and cutting area. When assembling this, start from the bottom and work your way up. The U-shaped connector pieces are intentionally smaller than the surfaces they fit around by the original designers. Use pliers to get even pressure when placing them in position. This prevents damaging material and breaking the process. I attached the part to the gantry with a simple zip tie. Without it, or an alligator clip like device, the part will fall off during operation. A zip tie is a sturdy connector that allows easy removal for maintenance or replacement.
