Both parts print vertically, join them together with 20mm M3 bolts.
The Linear bearings slide in and secure with a zip tie
It has a belt adjuster on one side of the belt clamps - see photos
The Extruder is based on Greg's excellent design, with a few mods and the extensions allow it to fit on the Quick-Fit X Carriage.
You need two x M4 (13mm) 624 bearings for the Quick-Fit Lever.
It also has a fan mount on one side.
It's designed to be expandable (easily made wider) by adding spacers between the two halves - without taking off the printer. - just in-case you ever need more room to fit triple extruders !
