MK3s Z spindle ball bearing

prusaprinters

<p>This is a little mod for the MK3s to add a 608 ball bearing per Z spindle at the top end.</p> <p>The Z motors need to be a few mm higher (additional length of the spindles at the top end to fit into the bearing) so there also new mounting parts for the Z motors. It may be necessary to turn the motors 90 degrees because of cables.</p> <p>It was a little bit tricky but now there are no more crash areas with other parts of the printer.</p> <p>Additional information: Don't force the spindle into the bearing. If the end of the rod, the spindle and the holes for the srews doesn't fit on their own (in all possible Z positions!) the bottom part of the motor isn't align properly. Maybe the parts are not accurate enough printed or you need some more time to align them.<br/> Without the bearing the spindle should stay in center on it's own. It's only to fix against vibration and stuff, not to correct a misalignment.</p> <h3>Print instructions</h3><p>PETG, at least 20% infill</p>
