This is a simple but effective 2mm thick TPU vibration/noise dampener designed for 40mm series fans, particularly for use with a BentoBox v2.0. When paired with the TPU Noise Isolator base, my BentoBox is noticeably quieter, and does not have the annoying buzzing sound that radiates through my P1S's side panels. One of the mounting holes was replaced with a slot, for cable routing flexibility within the BentoBox. This design works well in other applications using 40mm fans as well. I hope that you find this useful.

Cheers,
