Ultimaker Left Fan Duct Mod 2

thingiverse

The revised version addresses shortcomings of its predecessor, featuring improved tolerances and a closer hover to the build plate. The nozzle now points more downwards and to one side for better performance. Compatible with stock Ultimakers without interfering with blocks or requiring non-standard parts, it uses V2 hothead. To install, simply print without supports, attach the fan onto the shroud using two standard Ultimaker bolts, slide the shroud over the long bolts, and secure it with nuts. Ensure that it doesn't hit the print bed when zeroed. No special instructions needed.
