GeeeTech i3 Pro B Air Duct

thingiverse

I've created a new air duct design specifically for my GEEETech I3 Pro B after using XDr4g0nX's fan shroud for quite some time (thanks to their innovative design!). However, I believe my approach has several key advantages: * The base and throat of this duct are much more slender than before. As a result, it doesn't conceal as much of your prints and it avoids hitting the glass clamps. * Its height is adjustable within a 3.5 mm range, which can help prevent obstacles from getting in the way. * The ring has many more holes that direct airflow downwards instead of inwards. This cooling effect benefits your printed parts rather than the nozzle itself, resulting in significantly stronger airflow. I manufactured this design using PETG, and I'm happy to report that the included supports are easy to remove. A second version of this duct adds a mount for the BLTouch, but I haven't had a chance to test it yet. If someone could post an update on whether or not it fits, I would greatly appreciate it. June 3, 2017: I've updated the BLTouch version with some important changes: * I moved the BLTouch mount 3mm outside as the screws for attaching the duct and the BLTouch were coming too close. * I closed the 0.1mm gap between the BLTouch mount and the support structure to prevent printing in mid-air.
