Vibration damper Prusa MK3S

This is a remix of the "Vibration Damper v3" (jumbo size without hole) by lazzymonk https://www.thingiverse.com/thing:91720
His version works well (said my neighbours !) but doesn't exactly fit the grey rubber feet of my Prusa MK3S.
Mine has an extrusion of 16mm x 14mm x 2mm on the top body to perfectly accomodate the foot.

If you already printed the lazzymonk version, I included in the zip each part of the damper in a separate .stl file, so you can print only the top part if needed.
I printed mine in PLA, 0.3mm, infill 20%, strong enough to support the printer and 2 rolls above.

This is my first attempt to modify an .stl file on Fusion 360 !
