K8200 Z axis nut-holder anti wobbling and backlash

thingiverse

Replace the original nut holder by this one to reduce Z-axis wobbling and backlash. Inspired from http://www.thingiverse.com/thing:235494 and http://www.thingiverse.com/thing:166030 I use it in combination with http://www.thingiverse.com/thing:361064 and http://www.thingiverse.com/thing:135151 Instructions You need : 2 M8x1.25 Nut (you can get one from the original nut-holder) 1 9.5x15mm spring 2 M5x0.8 Bolt (Original nut-holder bolts) First, check that the smaller part can move freely inside the bigger one. You might have to sand the parts to have a smooth surface. Put the spring between the two nuts into the smaller part, so that the nuts can slide along the hole. Put the smaller part into the bigger one. Screw the assembly on the M8 leadscrew. Screw the nut-holder to the extruder arm with the two M5 bolts.
