These stabilizers replace the zip-ties originally used to position the LM8UU linear bearings on the Printrbot LC.
http://www.thingiverse.com/soke is developing a modified version for the PB+ V1.
The end result is a sturdier print bed and chassis for better printing. Inspiration taken from the official Printrbot stabilizer upgrade.
Volume: 2.12 cubic inches
ABS Weight: .08 pounds
- Print one left stabilizer and one right stabilizer. They're different parts, so don't mix them up! The left stabilizer has been confirmed to clear the Y endstop on the Printrbot LC.
Left Stabilizer requires:
2 #6-32 x 3/4" Screws
2 M3 x 16mm Screws
2 M3 Nuts
Right Stabilizer requires:
2 #6-32 x 3/4" Screws
2 M3 x 16mm Screws (screws into Y axis motor)
Attach the stabilizer plates to your Printrbot. Insert some folded paper between the bearing and the bearing slot(s) to adjust desired tightness. Don't tighten the screws down all the way yet!
- Slide the smooth rods through both bearings and tighten the screws. At this point you can try wiggling the rod around to test everything out. Keep in mind the feet and base of the Printrbot will deflect if you push hard enough, but your print bed will be secure! Be sure to not overtighten the M3 screws that screw into the Y carriage motor either, as stripping those threads will cause you problems.
Both parts will require supports to print successfully.
Drilling out the screw holes to the proper diameter may/will be necessary. (9/64" and 1/8" for #6-32 and M3 respectively, if memory serves.)
I recommend using the bed stabilizer in conjunction with my z axis stabilizer for additional robustness! http://www.thingiverse.com/thing:55053
