Inspired by TwoTimes awesome wobble arrester,

http://www.thingiverse.com/thing:2151

You will need to purchase the vertical rails and bushings listed in the wobble arrester materials list.

The design captures the Z-axis nut, have a smooth base which can slide smoothly under the acrylic and have a vertical pin to prevent rotation. it is all very simple and makes a huge difference in the smoothness of your prints because it removes the wobble from the rotating z-shafts.

I also printed a simple triangle to capture the z-rails, but the ones in the wobble arrester is far cooler.

Print 4 pieces. cut a 7mm pin for each and mount as shown in the pictures.

Pick up the Z-acrylic, remove the wood nut-stops

Then place one of the prints over each nut, with the pin facing out, pin UP naturally.

Replace the Z-acrylic and start printing smoother stuff.
