This is a centrifugal fan that can be 3D printed and is compatible with the Cannawiki grow controller. A motor driver such as the TB6612FNG is required so that it can be controlled. This fan is designed for the 385 motor to be driven at 12V, but most 385 motors can be run as low as 4.5V. ▼

This will work best with a well-calibrated printer, this design includes a lot of press fits. Some parts may require sanding after printing to fit correctly.
 
1. 3D Print all parts
1. 3D Print all parts[[File:385 fan mid assembly.jpg|thumb]]2. Solder wires onto the 385 motor if it doesn't already have them. (Optionally on the other end solder a 12V barrel jack)
 
2. Solder wires onto the 385 motor if it doesn't already have them.
 
3. Insert the motor all the way into the Motor mount. It will be a tight fit. Feed the wires through the case and bolt the motor holder into the case. Bolts should be pointing into the case, add the nuts on the other side of the motor mount. Once attached feed the wires back into the case through the slit.
 
4. Add the [https://cannawiki.net/wiki/index.php/File:385_case_bottom.stl Case bottom] on top of the case assembly so far. It should sit flat on the [https://cannawiki.net/wiki/index.php/File:385_Case_wall.stl Case walls] and be flush with the top of the motor holder. Screw in the 3 M4 bolts▼
 
5. On the side, put the prop adapter through the central hole of the impeller and tighten a nut on the other side.
3. Insert the motor all the way into the [https://cannawiki.net/wiki/index.php/File:385_Motor_holder.3mf Motor holder] and snap the motor holder into the case walls. It should be a press fit (Optionally add a dab of superglue to the bottom of the motor to help it stay in the motor holder.

The spacer will ensure there is clearance between the impeller and tightcase floor. Tighten the grub screws of the prop adapter.

7. Cover with Case top. This should clip into place and may require some trimming if it does not fit initially
1. Insert the 5mm * 20mm rod into the shaft coupling and tighten the grub screws to secure. Take care to keep the rod straight.

2. Add the [https://cannawiki.net/wiki/index.php/File:385_fan_blades.3mf Fan blades] onto the thread and tighten the M5 nut to secure them.
 
8. Solder barrel jack socket to the wires

The fan can easily be mounted with heavy-duty velcro, which makes for easy repairs
4. Cover with [https://cannawiki.net/wiki/index.php/File:385_case_top.3mf Case top]. This can be secured with tape so that the fan is easy to open up if needed
