Simple Prusa i3 Fan Rework

thingiverse

If you've got one of those ultra-budget Prusa i3 kits, this humble fan duct could just do the trick, and what's more is that it's an incredibly straightforward rework that adds a little extra cooling right near the hot-end - nothing fancy, just a bit of help when things get hot. Now, don't go thinking this is a permanent solution, because in reality it's meant to be replaced later on with something even better and more comprehensive. Here are your instructions: for the best results when printing this part out, make sure it's properly aligned so that the fan mount sits flat at the bottom - easy peasy.
