Fractional 80/20 Nut adapter

This piece adapts ordinary 8-32 nuts to the 80/20 aluminum extrusion system. Sketchup file is included for altering length and number of nuts. Instructions As much as it pains me to use Imperial units, this is designed for "10 series" fractional 80/20... The nuts' centers are 2.75 inches apart, but that's easy to change in Sketchup...
