Prusa Mini Y-Axis Bearing Holders

prusaprinters

<p>I wanted to try the Igus Drylin bearings on my Prusa Mini, but I wasn't happy using the original bearing brackets to mount them as it is very easy to over-tighten the bolts, pinching the drylins. The model this remix is based on holds the bearings much better, but it doesn't fit in a number of places on the Prusa Mini.</p><p>On the left side, the extrusion is too close and on the right side both the Z-axis bracket and the Y-axis motor are in the way.&nbsp;</p><p>This version looks a bit clunky, but I wanted to be able to be print it without supports. The high side is as high as it is, to prevent the bolt head to press against the bearing. The low side should be mounted using the original bearing bracket bolts.</p><p>Make sure to mount the bearing holder on the right rod with the thin part on the side where the Y-axis motor is. Press the bearings into the holder pulling the gap open a little bit.</p><p>Mounting requires 3 M3x16 bolts (make sure the bolt head is max 3mm high), 3 of the original bolts and the original nylon hex nuts. I used the Igus Drylin RJ4JP-01-08 bearings.</p><p>Print on its side without supports. I printed it with PETG, &nbsp;0.4mm nozzle, 0.2mm layer height, 3 perimeters and 100% infill.&nbsp;</p><p>Update 2021-06-15: It came to my attention that these holders work perfectly well with regular bearings as well. I therefore changed the title to reflect this.&nbsp;</p><p>&nbsp;</p>
