X-Leveling Spacer

UPDATE: For a version that attaches to the printer and retracts when not in use, go here: https://www.thingiverse.com/thing:3462192

UPDATE - 02/02/19: Reworded the Title and Summary to better describe the actual purpose/use of the spacers.

UPDATE - 12/15/18: Added a Rev2 version. Made it 5mm deeper and added a "handle."


Got tired of using a single piece of scrap aluminum and wanted 2 identical spacers for leveling the X-axis (formerly, calibrating the Z-axis height, a misnomer) so I came up with these.

They're 70mm tall and slip into the side rails of the gantry. You might have to enlarge the grooves a bit with a file or sandpaper based on your individual printer characteristics. Mine fit snug enough to stay in place but loose enough to easily slide them out after calibrating.

Dual Z-motors CAN and DO go out of sync, thereby "tilting" the X-axis. It needs to be level.

So, for EVERY print, I slip in the Spacers, adjust the leadscrews til I get the same feel between
