Fanduct for the SmartrapCore printing zone V.2.3

An Upgrade for SmartrapCore Fans This new fanduct was developed from a previous version I built for my printer. It features a lower angle, improving airflow by positioning it above the Zsensor's ring instead of below. A potential advantage of this design is that it may reduce collisions with other printer components during auto-leveling, like the RPI camera mount I designed: http://www.thingiverse.com/thing:678010. I also enhanced air exit efficiency and increased the printability of this new fanduct by making its shape more vertical. One potential drawback is that positioning it above the Zsensor's ring prevents adjustments if your hotend sits lower than mine, which has a 0mm offset. However, for most cases with a hotend under 8mm offset from the stock level, you'll be fine to place this fanduct below the sensor. This design proved optimal for my installation, and it will now officially be part of the SmartrapCore printer by SmartFriendz: http://www.thingiverse.com/thing:651117, alongside their other designs. A word of caution is required if your SmartrapCore has a horizontal wood piece in front - be prepared for a collision between this fanduct and that wooden support on the first homing cycles; I'm guessing the wooden piece will win the contest. Installation Instructions Before you start: This upgraded fanduct was specifically designed to work with SmartrapCore's revised lowered fan/hotend/Zsensor mount, either in V1.02 of their original package or as I've re-engineered it here: http://www.thingiverse.com/thing:819559. You will need a 40mm fan, along with four M3x16 screws and the nuts required to secure this fan in place, along with two parts included within this print file. Please plug your chosen 40mm fan into the available connectors on RAMPS board; it's up to you whether to configure your own custom settings.
