Printrbot anti-wobble Free 3D print model

The Basic Plastic Printerbot often creates visible bands on the sides of prints that align perfectly with the Z-threaded rod pitch. These bands are particularly noticeable on prints using slices thinner than .2mm. To track down the root cause, custom parts were designed to secure bearings and rods in place. Additionally, an external bracing system was developed to provide extra support. After investigating further, it became apparent that the Z-motors' tendency to rock back and forth was responsible for the bands. This unsteady motion causes uneven lift in the Z-axis, resulting in layers becoming distorted and bulging on the sides. By installing a few strategic wedges, this issue can be resolved effectively. Meanwhile, the other custom parts may prove useful for enthusiasts seeking a more robust printer setup or wishing to repurpose components for another project. Moreover, a crucial error was discovered in the original CAD files – the Z-motors are misplaced by .5mm. A revised and corrected version is currently available on Thingiverse (Thing: 26542). Further modifications are forthcoming as time allows; an optimized base design with enhanced motor support has been drafted, although it's likely unnecessary for most users. The associated files can be found on Thingiverse (Thing: 28557).
