Solidoodle Jigsaw Replacement Extruder mk5

An updated version that makes several improvements:

• Locking arm to prevent extruder wobble
• New and improved stronger tension arm
• New accessory mounting system which is cleaner and stronger
• Redesigned and streamlined filament guide to prevent filament accidentally escaping and allowing easier access for filament drive cleaning
• Improved built in support section for largest part for cleaner printing
• Added boss for left hand limit screw (to suit my replacement carriages)
• Revised mounting holes to allow greater compatibility with hot ends (should be compatible with E3D all metal hot end)

Update 1: End stop screws widened to ensure E3D hot end fitment. Thanks to OzAdr1an for testing.

Update 2: Bevelled edge body variant added thanks to 2n2r5. THis is to suit Printrbot hot ends or if you are having a hard time fitting your hot end.

Update 3: Filament guide replaced with pre-prepared version from foofoodog, should now slice for everyone.
