50mm Turbo cooling fan upgrade for Tronxy X3A.
As simple as it could but effective.
Use a fan with 0.15A or higher so you can get acceptable air flow.
You can use glue gun to hold the fan tighter to the duct.
The holes are 3mm, make sure you use a good length screws.
Might need some cleaning before installing the fan.
I designed it on onshape. I needed something simple, easy to print, and keep the printer style.
In the future i might upgrade this part to be modular fan duct.
