Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.

**This is an improved version of [thing 295317](http://www.thingiverse.com/thing:295317)**
##Goals
Fine detailed parts of your prints (PLA and ABS) normally don't show up well and and bridging only works for small distances if you use your printer like shipped from the manufacturer. This is because a fundamental part of your printer is missing - the extra cooling fan (duct). On some of the prints you can slow down printing speed as a workaround for this problem but you will not get very fine details or long bridges to match your needs. The goal of this duct is to create the best possible solution to avoid this problem without any real drawbacks.
##Compatibility
This active cooling duct is designed to work on the following MK7/MK8/MK9 Dual Extruders:
* MakerBot Replicator 1
* FF3DP FlashForge Creator
* CTC Creator Dual
* WanHao Duplicator 4 and Duplicator 4X
##Improvements compared to v1
* Higher air flow rates especially on the side channels
* Less air loss between fan and duct
* Only screws and nuts are required which are available in every hardware store
* Duct will be mounted horizontally and solid - enough space for small buildplate clips
* More flat center air outlets to avoid contact with heatblocks
* Angular fan mounting allows usage in Duplicator 4X with regularly installed and closed front door and avoids previous known crash problem…
