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:

No 3D printer? We sell a ready-to-use version in our Etsy shop.
We’re working on a bunch of other videos so be sure to subscribe to our YouTube channel so you don’t miss out!
Do you happen to have the gopro 9 black file? I sadly just printed 3 of these and they do not fit.
The only CAD file that we have publicly available was designed for the HERO7/6/5 GoPro Supersuit. However, we sell already printed versions for all GoPro models including the HERO9 Black Protective Housing + Waterproof Case. The Air Knives that we create for the newer GoPro models work a bit differently, and we have not made instructions on the newer models at this point.
