Inspired by the Pillow Block X-Carriage by AlephObjects - this is an X-carriage designed to be used with Igus Pillow Block Bearings, with room for an extruder fan mount on the rear of the carriage.

I specifically use this X carriage on MendelMax 1.5 printers.


  1. Simply download, print, and enjoy.

Depending on the calibration of your printer, the holes for the nut capture may be tight - if so, the easiest way to get the nuts where they need to be is to stick a screw through the hole, stick the nut on the end, and tighten until the nut is all the way seated in the nut capture hole. Then remove the screw and continue with the process until all of the captured nuts are in place, then install your new X carriage.

which fan mount do you use?

So the screw holes are designed to fit this thing:


But I'm still in the process of customizing both the mount and the fan - I've got the newer really short J-Head Mk VB, and there just barely enough room under the X smooth rods to fit the 34387 fan, but it drags on the underside of the X smooth rods in my MendelMax. I already had to redesign the mount from the 34387 in order to get the fan cowling to barely fit as it is.

I should have something that fits better uploaded within a week from today if not sooner.
