About this 3D model

I don't like using zip ties as structural components, so I made some LM8UU clamps. They require 2 10mm M3 screws, and two m3 nuts. If you use the nut trap, you can install 'em without using a wrench :-) installation vid: http://berthareprap.blogspot.com/2014/05/prusa-i3-graber-edition-mounting-axes.html
