Hi, the site stop to work as a shop, if you are interest, you can find the model here: CGTrader Shop https://www.cgtrader.com/sgabo...
This is a conversion kit for 120mm PC fans. The kit was born from an idea that proved to be very effective. This design has been tested on two 3.84 watt and 6 watt fans with doubling of pressure. Obviously the fan flow is halved. Equally obvious that the faster the rotor turns, the more pressure and flow is produced. I suggest using fans of 3 watts or more.
Dimensions supported by the kit
- The kit is made for an engine diameter between these: 36,37,38,39,40,41,42 mm
- The maximum height of the motor is 23 mm
In this video the assembly of the kit is shown and then the test is shown with a few calculations.
The design is optimized to be printed with 0.4mm nozzle
Among the files you will find two covers, the "cover-plus05" adds 0.5mm of space in height if you have not been very precise in installing the impeller. Or in case your motor moves too high.
I added rings with a thickness of 0.5 - 1 - 1.5 mm, but if the thickness you need is different, you can make a resize on the Z axis with the slicer to get the thickness you need.
Suggest print option for the impeller:
- Wall 0,8mm
- Top/buttom 0,8-1mm
- infill 10%
- support only touch bed and angle over 70% (you need have support only for the hole)
Normal radial fans have a dead zone of 20-25% which does not produce pressure, with this design there is no longer a dead zone and the whole fan is used to generate pressure. Not only that, more explanations in this video:
In this other video the first comparison test with a 6 watt fan.
