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

thingiverse

This extruder mount makes it possible to install the Flexion flexible filament extruder by Diabase Engineering in a direct drive configuration on the Anet A8 using minimal additional hardware. Solidworks files are provided 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, allowing it 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, requiring some force and tinkering due to a somewhat tight fit. 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 in. If unable to slide in the extruder, check the position of the heat break flat and make sure it is parallel to the motor shaft. 6. 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, moving the heater block down for more clearance. 7. Removing the full cover original flexion silicone sock allows for 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, providing more clearance. 8. Slot the extruder fan mount between the motor bracket opening on top. 9. 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, tightening to clamp the motor and fan holder onto the extruder mount. 10. 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. 11. Install dragchain holder if using the standard Anet A8 dragchain, as the dragchain holder model does not have bottom mounting holes due to space taken up by the extruder. 12. Insert the fan duct into the 50mm blower and attach with hot melt adhesive if necessary. Solidworks files are included, and remixes are encouraged.
