This temperature calibration model can be used to accurately determine the proper extruder temperature for the specific filament you are currently using. Each section of the model contains multiple testing areas to determine at what temperature you will have the best print quality.  
Temperature Tower Sections Include:

The bottom of the tower is made up of a section 0.4mm tall that expands in both the X and Y directions. This is used to determine if your current nozzle positioning is accurate or if you will need to adjust your leveling or Z-offset. Simply measure the base of this at all four points with dial calipers to ensure a properly calibrated Z-height.


Each section contains three small cones at staggered distances to test the amount of stringing and overheating that occurs when attempting to print very fine details.


The sections each have a diamond on one side with edges building out and in at 45 degree angles. This is conventionally considered to be a reasonable overhanging threshold for most 3D printers…

Как оказалось, заставить Ender-3 плохо печатать - довольно сложная задача)))) Поэтому некоторые примеры могут быть не самыми наглядными. Ломать принтер, чтобы он плохо печатал, как-то совсем не хотелось))))

A fellow maker frankybuilds, modeled a new Ender 3 mount solution for my fang including versions with and without an EZABL attachment. It requires less parts and it seems very easy to print. I don't own an Ender 3 so I haven't tested it but it looks very promising. Please give it a go!https://www.thingiverse.com/thing:3419869

If you'd like to use my fang design with an Ender 3 printer, please try the mount plate that D3Dorsett created here: https://www.thingiverse.com/thing:3157597

I added an additional variant that features a cable holder. The bowden tube & cables touch the 5015 fan on top so this cable holder extension prevents them from sliding left and right during the movement of the x-axis. You don't need this cable holder but it keeps everything in place as well as neat & tidy. Check the images. You can lock the holder using the same type of screw as for the 5015 fan (M3x22) or with just a zip tie.
