MK3S Vertical Fan Mounting Kit

Print fan is vertical and further away from the heat bed and heat block. Better cooling and open access to everything.

Description

The MK3S+ E-Axis stock setup is great as is, but I wanted easier access and orientation for my print fan, print fan exhaust shroud, mounting brackets, hardware, heater block and nozzle.  

The print fan will pull in cooler air because it is perpendicular and further up from the heat bed.

I printed with PETG at 0.2mm height and slower speeds.

Notes

  • I modified the Prusa stock extruder cover model to suit my needs for this kit.  
  • I'm including 1mm and 3mm washers to use as needed, especially if you don't have the right size bolts.
  • My fan wires are more exposed/longer than normal and you'll see that mine are wrapped around the lower support bracket; this is my preference and may not apply to you.
  • The extruder motor wires fit nicely between the motor and upper support bracket.
  • The missing heat sink cooling fan bottom-right bolt is missing on purpose; I may add some use for it eventually, but it's currently unneeded.
