Nothing unusual, I printed mine on their sides for the best strenght along the important axis, used supports for the LED Bar's mounting point but it doesn't really matter because the ugly parts get covered by the LED Bar.
This is only the top parts, for the rest of the Anti Shake Construction parts go to https://www.printables.com/model/705295-creality-ender3-v3-ke-anti-shake-construction
The author remixed this model.
Added the mounting points for the LED Bar to the model, replacing the original sheet metal ones.
