Anet A8 e3d v6 Bowden Print Carriage Redux

This is a combine work project between myself and Dan Rogers. The purpose was to create a print head mount that allows the user some customization to their exact/ or wanted setup This is for a Bowden setup. There are 4 variations of the mount:

           -Sensor with cooling fan
           -Sensor without cooling fan
           -No sensor with cooling fan
           -No sensor without cooling fan 

Many of the parts are interchangeable if you wish to make changes down the road as you upgrade/ change you own setup.

There is some required materials for assembly and they are as follows:

      - M3 Hex nut: 8 pieces
      - M3 Screw 25mm length: 7 pieces
      - M3 screw 20mm length: 1 piece
      - The 12 existing screws used to mount the existing carriage to the axis

You can use standard screws or socket head screws

Printing

You will want to use some supports when printing the PRINT CARRIAGE PLATE and the HEAD LOCK. DONT use supports when printing the cooling fan duct.

See the images for the recommended part orientations when printing.

Assembly

Prior to assembly, you will want to press fit four (4) M3 hex nuts into the carriage plate, two (2) into the head lock ( the two slots along the top, confirm they align with the screw holes) and 1 into the fan mount (again confirm they align with the screw hole)

Step 1: Attach the belt holder to the back of the carriage plate ( be sure the opening is facing down) Use four (4) M3x25 screws to do this.

Step 2: Attach the print carriage to the bearings on the X axis. Using the existing 12 screws. It is recommended using the cross tightening method. Then once all screws are in tighten them all down

Step 3: Place the e3d v6 into its opening on the print carriage and attach the desired head lock (fan or no fan). Using two (2) M3x25mm screws This will be a snug fit

At this point if you are not using a sensor or the fan your carriage is completed

Step 4: Attach the turbo fan (5015- radial cooling fan) using one (1) M3x20 screw on the upper most hole and one (1) m3x25 screw on the lower hole

Step 5: Attach the cooling ring to the turbo fan

At this point if you are not using a leveling sensor your carriage is completed

Step 6: Attach your leveling sensor (proximity or inductive) to the mount using the included hardware with the purchase of one.

FINAL STEP FOR EVERY VARIATION
Secure your wires with a zip tie through the slots on the side of the print carriage. This is HIGHLY recommended as stress relief.

Sensor
This thing is designed for an 18mm sensor or a 12mm sensor. So when choosing your print carriage, be sure to select WHICH file you want.

Sensor offsets
With this design the offset of the center of the sensor to the center of the nozzle is:

           **-28.873mm**

Please post make pictures if you print and use this print head!

EDIT 2/15/2016

The Co-designer Dan Rogers has released a new cooling fan duct that works along with this print head at the following link. http://www.thingiverse.com/thing:2086437 . The goal was to create a lower profile cooling duct.
