Robo3D Z Rod Constraint

thingiverse

Description This ensures a stable threaded Z rod, eliminating wobbling and minimizing Z ribbing, particularly when paired with a Z isolator such as the one linked here: https://www.thingiverse.com/thing:1122480. Instructions Required Materials 2 x 608zz bearings 2 x M3 socket head bolts (12mm long) 2 x M3 nyloc nuts Assembly Instructions Print two identical units. Securely press-fit the bearings into their respective spaces using a hammer and block of wood, ensuring full insertion. Insert nyloc nuts, followed by the bolt; semi-tighten the bolt, allowing for easy sliding onto the smooth rod. Adjust the threaded Z rod to a vertical position on the smooth rod before tightening the bolt securely. Print Settings Printer Details: Robo 3D - R1 ABS + PLA Model Printing Parameters Rafts: Optional (not recommended) Supports: Disabled Resolution: 0.3mm Design Notes The design assumes accurate printer calibration; no tolerance is built-in. To achieve optimal results, adjust your printer's XY offset in Slic3r or S3D. Recommended print settings include 3 perimeter shells and 2 layers for the top and bottom surfaces.
