3D model description
When the z-height of my original Prusa i3 MK2S is about 30 mm, the threaded z-axis touches slightly the original (ABS printed) "Z-axis-top-part" and when these elements touch, they generate an irritating vibrating noise while printing. There are many comments on Thingiverse and on the Prusa forum stating that the threaded Z-axis should move freely, which also sounds logical to me.
So to overcome this irritating noise I made this damper which, when printed in a flexible filament, takes away the noise. The wall of the damper is only ~0,4 mm thick and consequently the z-axis has - I believe - still sufficient room to 'wobble'. The damper fits snugly in the hexagon shaped recesses of the z-top-parts.
I printed a set in TPE with a shore hardness 45D. The left damper is a mirror of the right damper and they are marked L and R to make sure you install these on the right place. So far this works fine for me and I have not seen any negative effect on the print quality. Let's see how long they will last :-).
The last photo shows the threaded z-axis touching the damper (z-height at 30 mm) while the other photos show that the z-axis moves freely in the z-top-part including damper.
Pls let me know what you think.
