Projector Cooling Fan Upgrade

prusaprinters

I have a cheap unbranded projector that worked fine for its price. The only issue was the internal cooling fan was unbearably noisy from what I assume was a bad bearing. Instead of buying a replacement fan, I decided to design and print a duct to mount a computer fan I had laying around. The advantage of the computer fan was it is essentially free and the much larger blades equated to near silent operation. The computer fan had the same voltage and current draw so I could wire it directly to the projector. I used a fabric luggage strap to attach the duct and a foam insulation tape to create a good seal between the projector vent and the duct.   The duct has loops to mount the fan wires with cable ties. There is also a recess in the side to allow clearance for the HDMI port of the projector.Materials:3D printed ductFabric strap (to attach duct to projector)Foam insulation tape (to fill in gap between projector and duct)120mm computer fan with mounting screwsPrint instructions:Layer height: 0.20mmSupports: YesInfill: 20%
