I built a DIY laser engraver around the Comgrow 10W laser module, and decided to design an air assist for it that replaces the existing laser shield. This should also fit the Comgrow Comgo Z1 module. This will work with a ~6mm air hose, which is what came with my Simple Deluxe aquarium pump. STEP files are included for mods.

The new shield is the same size as the old one, so laser focus is still 7mm below the edge. The air nozzle does stick out another 1.5mm on one side, so be careful not to focus from there.

I'm currently using the version with a 1mm nozzle opening, but also included a model with a 1.5mm nozzle opening for those who want to try it.
