3.5" hd frame limiting vibrations by DorianGrey

This is a remix of https://www.thingiverse.com/thing:2388396 but for some reason thingiverse won't let me connect to it as the source. I think it is safe to say that the thingiverse web-ui still hasn't recovered from the 'upgrade' it fell victim off a year ago.
So, in my lab computers often are half open with hard drives connected in a adhoc fashion (for larger backups or checking older drive' content) and often it's not really worth the time and effort to propperly mount them in the drive cage so the drives may actually balance on matchboxes or something.
For that I wanted a solution that is nore stable, still flexible and the last aim, should be anti-vibration and as such anti-noise.
I found 2388396 which provides a very stable upper/lower double frame intended to place elastic pins between them at the 4 corners. Only, those elastic pins were missing and the source recommended some 3rd party parts you may or may not have lying around.
So my addition to the project is that: elastic cylindric pins which fit into the four corner holes and provide the vibration/noise dampening. You need to print them with TPU or similar to actually be elastic and useful.
My first go was to do everything in TPU and make the pins a part of the lower frame It's ok, took half day to print with TPU needing to go so slow and there was lots of stringing.
So I tried a second setup, printing the upper frame in PLA which goes faster and is very stable and then add 'feet' for it printing the 30 mm pin in TPU four times. The lower frame is not needed.
The FreeCAD source file is included so you can fine tune the model to your needs.
