Anet A6 E3D Hemera Carriage

###Anet A6 E3D Hemera Carriage

This carriage design for the Anet A6 3D printer is suitable for both the E3D original Hemera and the shorter and lighter E3D Hemera XS extruder.
The parts are added to equip the Hemera with the E3D Revo, V6, Volcano or SuperVolcano hotend, such as a straight or circular fanduct and BLTouch mounting options.

A height difference of 4 mm between the nozzle and the fan duct/ BLTouch gives the possibility to clamp a glass print bed with simple binder clips without the lose of much buildspace. Only with the shortest V6 hotend there is a maximal clearance of 3.5 mm for print bed clamps due to the distance between the nozzle and the slide bearings.

Four LM8UU linear bearings are used. Plastic Igus linear slide bearings with article number RJ4JP-01-08 are prefered for its lower weight and noise reducion. These bearings are pushed in the basic part where they will be locked in place.

Like with the Anet extruder, the timing belt ends are looped trough t
