Printrbot Y-Axis Mod

thingiverse

Easily level your printer bed by filing down the PB-Y axis bar mounts on the high side, and improve accuracy and endurance of your 3D prints with this minor modification. Printing the standard lasercut wood for Y-Axis bar mounts and clips can cause issues due to tight tolerances that scrape against the Y-Axis pulley gear. This mod involves raising the bed by 3mm, increasing PB-Y bar mount width for better rod grip, and making belt clip base thicker for proper alignment. All files are configured for ABS plastic, and Gcode is centered for both 6 inch and 8 inch Printrbot models. Printing all parts together is recommended as they work as a package.
