Ender-3 Micro switch Bumper - or any other printer with the same micro switch

One of the first parts I designed and printed, was a tiny bumper to damp the load "bang" every time the printer started working. My idea was to avoid the metal-to-metal contact at every start of a print job. Note the orientation as it is not symmetrical—the thinnest part between the lever and the micro switch body.(There are 3 of them, one for each axis)
