The "5th leg" for K1C - anti-vibration TPU damper for the bottom plate

In contrast to my previous model (Ender3S1Pro feet) posted on Printables, this part aims explicitly at vibration/noise damping and nothing else.

I made this damper originally with 24mm in height, which in my case looks just sufficient for touching the bottom plate and stopping the vibration noises. Afterwards i came to the conclusion, that a height of 25 or possibly even 26mm might work better in my case (however, i am not quite sure about that). 

So, i decided to give you a choice, which one you would like to make for yourself. 

My suggestion regarding the printing settings (based on my unscientific experiments) is to print this part with TPU95A using a 0.4mm nozzle and:

• 3 top and bottom layers
• 2 wall loops 
• Alternate extra wall
• roughly 16% Gyroid infill (i guess this is the most important*)
• (optionally) 0.24-0.28mm layer height (basically to speed up the print) 

* This settings should make the damper soft and squishy, so it can also easily be pushed under the bottom edge of the printer frame with no need to lift it up.

PLEASE make sure to position the damper so that it does not cover any of the ventilation holes at the bottom of your printer. 

Have a nice print!
