Anet A8 Flexion Extruder Direct Extrusion Mount For Flexible Filaments Also Compatible with Similar Prusa I3 Clone Variants

This extruder mount allows the Flexion flexible filament extruder by Diabase Engineering to be mounted in a direct drive configuration on the Anet A8 using minimal additional hardware. Solidworks files included for any modifications to dimensions or tolerances.

Additional Hardware Required:

For Extruder Mount:
3X M3 Nuts
1X M3x30 Bolt
2X M3x12 Bolt

For Extruder Fan Mount:
2X M3x12 Bolt

Assembly Directions:

1. Remove all original extruder hardware leaving only the bracket on the Anet A8.

2. Assemble the Flexion Extruder as shown with the flats of the heatbreak parallel to the motor shaft. This will allow the extruder to slot into the original Anet A8 bracket.

3. Print the extruder mount and fan mount using the print directions below.

4. Slide the extruder mount onto the Anet A8 bracket through the linear bearing bolt heads. This is somewhat of a tight fight and will require some force and tinkering.

5. With the extruder mounted onto the Anet A8 bracket as shown, slide the Flexion Extruder/Motor assembly into the mount and ensure it is seated all the way into the mount. If you are unable to slide in the extruder, check the position of the heat break flat and make sure it is parallel to the motor shaft.
   If there isn't enough clearance between the heater block and the metal bracket, reassemble the Flexion extruder with the nozzle tightened further into the heater block and the heat break loosened further up. This will move the heater block down and allow for more clearance.
   Removing the full cover original flexion silicone sock and either running the extruder without a silicone sock or using an alternative silicone sock such as the E3D silicone sock which does not cover the top of the heater block will allow for more clearance.

6. Slot the extruder fan mount between the motor bracket opening on top.

7. Insert a M3 nut into the motor bracket nut trap and put the M3x30 bolt through the motor bracket holes and the fan mount holes and tighten to clamp on the motor and fan holder to the extruder mount.

8. Insert M3 nuts into the nut trap on the rear-bottom of the extruder mount and use the M3x12 bolts to secure the entire assembly onto the Anet A8 metal bracket.

9. Install dragchain holder if the standard Anet A8 dragchain is being used. The dragchain holder model doesn't have bottom mounting holes since the space is taken up by the extruder.

10. Insert the fan duct into the 50mm blower and attach with hot melt adhesive if necessary.
