Ender 3 V2 X-Axis Spacer

thingiverse

Worked great on my Ender 3 V2 as a Pause/Resume fix. I have my filament spool mounted behind my machine and to clean up the entry of the filament I rotated my extruder 90 degrees. I first saw that idea over on CHEPs youtube channel where he discussed his rear mount spool holder. You can find that video here if you're interested https://www.youtube.com/watch?v=ttPl8WxwHwE Problem is while prints have been perfect since then there has been an issue of the print head assembly not staying firmly against the x axis end stop switch because the PTFE tube presses against the vertical rail slightly when fully to the left. Because of this when I need to occasionally pause and then resume a print the nozzle would never line back up properly and ruin my print because that pressure on the PTFE tube would force the print head a mm or 2 from home. This solves that by taking some of the slack off the PTFE tube and allowing the print to resume in it's original location. I'm not too worried about this but another bonus is that this also limits the strain on the PTFE bending a little around the vertical rail by offsetting it a bit.
