Printrbot base with z-motor support Free 3D print model

The new plastic printrbot base keeps the z-motor stable, allowing it to move smoothly without rocking like its standard counterpart. For added stability, you can use linear bearing clamps instead of zip-ties to hold the y-bearings firmly in place. These clamps have 4 holes for screws and I've even added 2 extra holes, not because they're essential but so you can opt for fewer if needed – although using 2 may work just as well. Zip-tie slots remain available if you still want to use them. Moving the motor 0.5mm has adjusted it perfectly with the space between the Z-nut and smooth rod. More improvements have been made, too. Additional features include tapping holes for screws that lock the smooth rod securely in place, as well as mounting holes that enable securing the base down with screws if you prefer. Although the Y motor works efficiently without any changes, I've included support to add later since I can. So far, Z+Y is functioning smoothly. However, one issue persists: limited spanner access. To address this, I've enlarged the hole in the CAD file, though it remains uncertain how effectively it will improve accessibility. Lastly, a test print was successfully made at 0.1mm resolution with barely any noticeable ripple visible.
