FanDuct 4020 fan

Many different fanducts have already been designed. But the right one for me wasn't there yet. So I started designing one myself (I'm a beginner in 3d design). I have seen several ideas, and have put them together. With the following result. Considerations that were important to me: A somewhat quieter 4020 radial fan is used. The original position of the BL-Touch is preserved, so that 2 LEDs can remain in place to provide some light at the nozzle. It had to stay simple. So there are only three parts in this construction. It is possible to use the original 4010 axial fan, but a 4020 axial fan can also be installed without modification. I designed this for a Creality Ender 5 Plus with a MicroSwiss hotend. But I think it also fits well on the original hotend. I can't check, but it might also fit other (Creality) printers? Assembling is easy: The 1st part is attached to the back plate together with the hotend. The axial 4020 fan is attached to the 3rd part. The 2nd and 3rd part can be loosely put together. After this, the 2nd part can be attached to the 1st part together with the axial fan. Finally, the height of the duct can be adjusted and parts 2 and 3 can be secured together. In addition to the 4020 radial fan, only some M4 bolts in different lengths and some M4 nuts are needed. And of course some wiring of the fans has to be soldered as well.
