Titan Aero - AnyCubic i3 Mega / Prusa i3 - Very hard for fast and high quality printing

I created this model because all other models do not have sufficient rigidity for high quality printing.
I use bronze bushings because they have minimal play, but you can use any standard size bearings - 4 short or 2 long.
I use cotton swabs around the motor so that the motor is rigidly fixed, while the platform for the motor is not too thick, and the sound from the motor is not transmitted to the printer.
The operating temperature of the motor is 35 degrees, not a large radiator is enough to
