Y-Undercarriage with belt spacing mod

thingiverse

This reworked design by SGK integrates multiple good ideas into one, simplifying the installation process. Instead of separate bearing holders and belt clamps, this version takes only 5 minutes to install with precise results, without any measurements needed. The design has also been enhanced with a few tweaks, such as adjustable space from the print bed to the belt to prevent angle-related issues. Additionally, two belt tighteners have been reduced to one for streamlined functionality. The SCAD code is cleaned up and commented for easier understanding, while the belt clamp module has been unified to create various shapes using appropriate parameters. Moreover, bridging layers have been added in nut traps for cleaner printing. The provided STL is for SAE #6 screws and GT2 belts; users can modify the SCAD file for other sizes or types of bearings/clamps. Note that linear bearing holder's SCAD file requires manual configuration adjustments. To assemble, drill appropriate holes in the print bed and secure the assembly using temporary screws before drilling clearance holes for belt clamp screws. Finally, place nuts in the clamp nut traps, fasten the assembly to the bed, and attach the belt with simple caps and tighteners.
