Prusa Mini Copperhead™ Hotend Adapters

No additional gcode nor firmware change required!

Absolute and relative positions of MINDA and nozzle are stock. PLEASE make sure to go through the entire Calibration Wizard, including setting MINDA height, after installing this thing.

I have been testing this thing using Prusament PLA/PETG for over a month to insure that the front facing flow approach works. The Mini does not have space for the traditional side mounting flow without additional gcode and/or x-Carriage modifications.

There are two adapters. One for the Groovemount and one for the Screwmount. The Fan Reducer works for both.

• Follow Prusa's guide to disassemble the stock Mini Hotend
• Reuse the top heatsink and MINDA mount screws as-is
• Use the bottom heatsink and fan mount screws to mount the fan to the reducer
• Use the Copperhead zip-tie screw to mount the reducer to the heatsink
• Use annotated pictures for additional install steps

Additional hardware:

• PTFE tubing: Length dependent on extruder attachment method
• 3mm hex nut for top of adapter (should have in extra parts bag)
• IF using stock extruder mount, brass compression ring (also in extra parts bag)

• IF using Festo style extruder mount, PASS-THROUGH pneumatic fitting
