Igus Drylin Y-Axis Bearing Holders - i3 MK3S

prusaprinters

<p>I designed these bearing holders to better fit the genuine Igus Drylin Bearings on the Prusa i3 MK3S. The MK3S is the printer I own and no other printer is tested.</p><p>The U-bolts that come with the printer tend to deform these bearings so that they don't travel smoothly and another holder found on here tends to mess up the Y-Axis length test so that it fails most of the time.</p><p>These holders use the same nylock nut that comes with the printer secured with a socket-head M3 screw.</p><p>These holders have two ribs inside to ensure that the bearing stays perfectly centered in the holder and to the slot in the Y-Carriage.</p><p>These holders allow the bearings to make contact with the frame so that the correct Y-Axis length is determined at the test passed. (These holders passed the test on the first try.)</p><h3>Print instructions</h3><p>These holders are symmetrical and should be printed upright with ZERO supports. The holder will be a snug fit into the Y-Carriage and will not be flush with the Y-Carriage with fully secured.</p><p>Obtain Igus Drylin Bearings.
