Brustruder is the final product of a preHuxley mini Mendel development by SpaceXULA named Brutis. Due to the small size of a Huxley, an extruder much smaller than a Wades would be needed for the X axis. This extruder was SpaceXULA's attempt to make a smaller, more reliable gear driven extruder than what was available at the time.
