You can place this pad underneath your speake to reduce the trafer of vibratio. Note that this design won't help if you print it in rigid materials like PLA, ABS, etcetera. I printed it in ColorFabb nGen Flex, but any (semi-)flexible material should work fine! The print orientation should be like the render, but when you place it underneath a speaker, you should flip it (the side that was attached to the print bed should be touching the speaker). If you have a larger or smaller speaker, you can scale the x and y size of the deisgn. I would suggest leaving the height at 10mm, as decreasing this could hurt the vibration dampening properties of this design.
