Volcano Compatibility Hot Fin for Short Ears MK3 and MK3S Extruders

thingiverse

Short Ears MK3S and MK3 Extruders Gain Enhanced Performance with E3D Volcano Capability. This Kit Moves the Print Fan and Shroud 8.5mm Lower to Match the Volcano Nozzle Position. Must Be Used with B02M5 or Later Short Ears Extruders Equipped with Two Fan Mount Positions on Their Hot End Covers. Slide the Square Nut of the Hotend Cover to Lower the Fan Hole Position, You Will Need to Push Past the Slight Resistance Just Below the Upper Mount Position. Then Replace the Existing Hotend Cover Hot Fin with the One Included in This Kit. Remember to Also Lower the PINDA to Match the New Nozzle Position. The Hot Fin Includes an "Evan Hook" Interlock Feature for Fan Shrouds Like the BNRHD Fan Shroud in BNBSX Extruder Projects. The Hook Prevents Right-Side Shroud Tilt in Case Mounting Screws Loosen. Bunnies Also Recommend Using M3 Nylock Nuts Instead of Regular M3 Nuts at Fan Shroud Mounts. Caveat: Firmware Modification Will Be Required to Pass XYZ Calibration Due to the 8.5mm Reduction in Total Z-Height Compared to Regular MK3S Extruders. The B03M2 Update Fixes Interference with "Evan Hook" RHD Fan Shrouds.
