Printrbot Z Axis Stabilizer

thingiverse

Print two of either the regular or low-profile Z stabilizers to reduce wobble on your Printrbot's Z-axis smooth rods. These stabilizers are compatible with the bed stabilizer upgrade found here: http://www.thingiverse.com/thing:43200. Designed for a Printrbot LC, a Printrbot Plus version is also available for 12mm rods, although it remains untested. Standard thickness is 0.25 inches, with a low-profile option at 0.20 inches; use the latter if your printing surface isn't raised by glass or leveling screws. The Z stabilizers have a volume of 0.4 cubic inches and an ABS weight of 0.01 pounds. To install, first remove the X carriage, Z axis smooth rods, and two pairs of screws in front and behind the rod hole. Test-fit the smooth rod into the stabilizer's center hole; it should be snug but manageable by hand. Scale down the print or adjust settings if necessary. Install the stabilizers with their bumps facing the Printrbot center, using two #6-32 x 3/4" screws for each. Don't tighten these screws until you reattach the X carriage for alignment purposes. Reinstall the rods and X carriage, tightening the screws before turning on the printer and zeroing the Z axis. If your X carriage hits the stabilizer, switch to the low-profile version. Be careful when handling smooth rods as mishandling can cause damage. For optimal results, use these Z stabilizers in conjunction with the print bed stabilizer upgrade found here: http://www.thingiverse.com/thing:43200.
