GoPro Air Knife for CNC Machining

Every time we try to film in a CNC machine, we always end up covering the lens in coolant:

Constantly stopping the machine to wipe off the lens was getting annoying, so we designed an air knife that allows us to clean off the lens from outside the machine:

We got this idea from an excellent series of videos on the Edge Precision YouTube channel. We designed the air knife in Fusion 360, and then printed it in PLA:

The YouTube video above shows the results. Here are all the files you’ll need to make your own:
