Air compressor, hose connection. Male&Female

thingiverse

If it's free, it's more than okay. I took my air compressor's threaded end that matches a 9mm hose and made a custom fitting to connect them securely. My compressor can reach up to 12 bar, so the connection needs to fit perfectly to prevent any damage or leaks. To get a precise fit, simply print the piece using a low-res setting (<0.1) and continue sanding until it slides on smoothly.
