Ford Brake Fluid Adapter

To change the brake fluid in my Ford, I needed an adapter that wasn't included with my brake fluid changer. The adapter costs over €70, so I made it myself. The prototype already fit, which is why it doesn't look quite as good in the pictures. You'll need a 1/4-inch air plug with an M14x1.5 thread. For the seal, simply use the seal from the original cover. Drill a hole in the center of the original seal so the brake fluid can flow through. Print the lid upside down to ensure the sealing surface is as smooth and even as possible. I printed the prototype in PLA. While that worked for me, I recommend printing the lid in a more rigid material like PETG, ABS, or ASA.
