Printrbot Bed Stabilizer

thingiverse

These replacements for zip-ties enhance the stability of LM8UU linear bearings on Printrbot LC. A modified version is being developed for PB+ V1 by soke. The result is a stronger print bed and chassis, inspired by official Printrbot stabilizer upgrade. It occupies 2.12 cubic inches and weighs .08 pounds in ABS. Print two distinct stabilizers: left and right, ensuring correct placement as left stabilizer clears Y endstop on Printrbot LC. Left Stabilizer requires 2 #6-32 x 3/4" Screws, 2 M3 x 16mm Screws, and 2 M3 Nuts; Right Stabilizer demands 2 #6-32 x 3/4" Screws and 2 M3 x 16mm Screws (screws into Y axis motor). Attach stabilizers to Printrbot, adjusting tightness as desired with paper. Slide smooth rods through bearings and tighten screws, testing stability before overtightening. Be cautious not to overtighten M3 screws that attach to Y carriage motor. Note that supports are necessary for successful printing of both parts, and drilling screw holes may be required for proper fit. Combine this bed stabilizer with the designer's z-axis stabilizer for added strength; instructions available at http://www.thingiverse.com/thing:55053
