12 mm Tee Nut 10 mm thread for Minimill

thingiverse

People who have a minimill often use a 12mm plastic T nut to hold lightweight bits and pieces such as clock gauges. This type of nut is not suitable for holding parts being machined unless they are made of plastic or very light. The nut has a 10mm thread, but it may need to be cleaned up with a tap or a 10mm bolt that has a slot cut lengthwise down the thread. Three different thread sizes are available: 10, 8, and 6 mm.
