Small footprint J-head quick fit extruder

Smaller version of Olekdh's extruder keeping all the good bits like the tilting screws, j-head lock plate and clean printing body.
The intention is to make an x-carriage that will take two of these either nose to tail or, if I can work out how to do it, mirror image.

I have rotated and moved the motor to allow the rear mount to be moved closer and shorten the whole baseplate, and should make it possible to mount these forward to back on the x-carriage.

Also has the standard 50mm spacing mounting screws too so will replace any standard extruder.
