Ender 3 - Gantry Leveling Tool

thingiverse

This remix of CheckXGantry by ninne allows for a more accurate gantry level by leveling off the frame rail of the Ender 3 instead of the bed. It accommodates M3, M4, M5 screws and some T-Slot nuts that are likely already on hand. To use this version, you'll need to print some additional T-Slot nuts if they're not readily available. You can find suitable designs at thingiverse.com, specifically https://www.thingiverse.com/thing:1686927. There are two versions of the nut design, one with a 3mm mounting hole and another with a 1.5mm mounting hole. These variations cater to different M3, M4, M5 screws and screw heads, expanding the range of possible uses. This solution encourages users to work with what they already have on hand, even if their screws are slightly too long. Simply stacking T-Slot nuts or washers can provide the necessary spacers for a proper fit.
