Replacement Knob for Angle Valve

Replacement Knob for Angle Valve – Double-Flat (8mm - 6mm Flats)During a renovation of an old house, I found that every single angle valve had stopped working. Upon closer inspection, I realized that all of them had faulty plastic knobs that had cracked or failed—seemingly designed for obsolescence. When I learned that replacements for just the knobs weren’t available, I felt the urge to create my own. Angle valves are cheap, but it felt incredibly wasteful to throw away perfectly good valves just because of a broken knob—especially for people who aren’t comfortable changing the whole valve and would need to call a plumber for it. This 3D-printable replacement knob is designed for angle valves with a double-flat (D-shaped) stem measuring 8mm - 6mm (flat-to-flat). It works flawlessly for me, and I wanted to share it with others who might be facing the same problem.If you're interested, I can also share the Fusion 360 file for modifications or improvements. Hope this helps someone ke
