I have an Elegoo Phecda 10W which at the time you couldn’t get the air assist for. So I designed my own air assist (similar to yours).
A test print caught fire (card), and this melted the air assist nozzle (PETG). This, in turn, covered the lens with PETG. While trying to clean it, I broke the glass protection. I now have a new air assist nozzle with an in built 20mm x 20mm glass slide cover to protect the laser. Not ideal, but Elegoo don’t have spares yet.
Be careful with it.
