Hard drive acoustic isolator

Tired of a hard drive that would cause my entire desk to resonate and amplify the sound significantly, I designed this acoustic separation mount for it. Measurements are roughly based on the following design: https://www.thingiverse.com/thing:1566237

This will accept any 3.5" drive, and I have found it to have reduced volumes to close to imperceptible over fan noise and has completely eliminated all vibration/resonance issues.
