Ender 3 - Gantry Leveling Tool

thingiverse

This is a remix of CheckXGantry by ninne, this version allows you to level your gantry off of the frame rail of the Ender 3 instead of the bed, allowing for a more accurate gantry level. It takes into account the use of M3, M4, M5 screws (so whatever you have lying around) and some T-Slot nuts. You'll want to print some T-Slot nuts if you don't have any lying around. I used these https://www.thingiverse.com/thing:1686927 There are two versions one with a 3mm mounting hole and one with a 1.5mm mounting hole to account for various M3, M4, M5 screws and heads to allow a greater range of use. This really is a use what you've got solution, if your screws are too long, stack up on the T-Slot nuts like I did, they're quick to print and work well as spacers! (or if you've got washers)
