LM8UU Clamp for Graber i3

thingiverse

Rather than using zip ties for structural purposes, an alternative solution is to create LM8UU clamps. These clamps require two 10mm M3 screws and two m3 nuts. The use of a nut trap allows for easy installation without the need for a wrench. To make these clamps, print one clamp and one nut trap using fine layers as they are delicate parts. Place the nuts in the nut trap, add your LM8UU bearing, and screw them in securely with the M3 screws. For detailed instructions, refer to the installation video available at http://berthareprap.blogspot.com/2014/05/prusa-i3-graber-edition-mounting-axes.html.
