A turbofan for your desk, with 20 swept fan blades, a spinner with the classic spiral, stator vanes and a tail cone. It stands on the base of the Turbo Desk Fan and uses the same motor, coupling and speed controller, so you can swap one for the other. Every engine part prints without supports.

Inlet, fan case and bypass duct in one piece, with the stator vanes and a Ø42.7 mm motor sleeve in the core. Vents in the core let the motor breathe; the wires leave through the lower fairing.
Screws to the motor's front face (2 × M4 × 8 countersunk) and to the front of the core (3 × M3 × 12 countersunk), so the motor sits at exactly the right depth.
20 swept blades on a hub that takes a 5 mm flange coupling (4 × M3 × 6). It goes in through the inlet; the set screw is reached through the open front of the hub.
The nose cone with the classic spiral. It presses onto the ring at the front of the fan hub.
Core cowl, exhaust nozzle and tail cone, with an air chamber behind the motor and six vent holes that come out in the nozzle. Three filament pins hold it on the core.
Holds the engine on the base. The motor wires run down through it.
The base of the Turbo Desk Fan, with the speed controller and the DC jack. Included in the ZIP.
For a 0.4 mm nozzle. Filament amounts are estimates for these settings.
The engine parts need no supports. Print the fan with good part cooling for clean blades.
Solder about 60 cm of wire to the motor. Screw the motor plate onto its front face with 2 × M4 × 8 countersunk screws, the bearing boss in the centre hole.
Feed the wires into the sleeve through the inlet and out of the channel in the lower fairing, then slide the motor in until the plate sits on the core. Fix the plate with 3 × M3 × 12 countersunk screws.
Push the three filament pins into the holes at the back of the core and press the tail on.
Screw the flange coupling into the recess at the front of the fan hub with 4 × M3 × 6, boss pointing forward. Slide the fan through the inlet onto the shaft until the hub is about 2.5 mm from the motor plate and tighten the set screw with a 1.5 mm hex key through the open front of the hub. Turn it by hand: it should clear the fan case by about 1.5 mm all round.
Press the spinner onto the ring at the front of the hub. It pulls off again if you need to reach the set screw.
Set the nacelle on the pylon, pass the wires down through it and screw the two M4 × 25 screws up through the pylon into the nacelle. Fit the controller and jack in the base (see the Turbo Desk Fan), then bolt the pylon onto the base with 4 × M6 × 20, washers and nuts from below.
Connect the motor to the speed controller and start slowly. If the air blows forwards, swap the two motor wires.
The fan spins fast. Only run it fully assembled, keep fingers out of the inlet and start at the lowest speed. Use a plug-in power adapter unless you know how to work safely with mains power.
A working desk fan shaped like a car turbocharger, with a speed knob in the base.
