The default setup for the Rostock MAX mounts the extruder motor underneath the top plate of the machine. This mount replaces the stock location in favor of mounting above the top plate. This is a far better location in case you have built an enclosure for your build area; the stepper motor will be kept much cooler. Revision A includes models for a spool holder that allows the mounting of an 80mm cooling fan director at the stepper motor, as well as a vented faceplate on the opposite side to help facilitate airflow. I noticed that the new location of the stepper motor interferes with the hanging of some large spools (oops!) so as a temporary band-aid I increased the height of the spool holder by 4mm. This rotates the spool arm just enough to prevent the interference, but expect a revision B at some point in the future with a proper fix. Revision B has arrived! All the files are the same except for the addition of the new spool arm. This spool arm is both higher and longer than stock, so it should handle oversize spools (including the 3lb trimmer line from Amazon) without the stepper motor getting in the way.
