3D printable PC case pads
Grrh }=
If your PC case have broken pads (as a mine server case), go and grab my project at https://github.com/WhiteFossa/PC_Pads_3D
It allows you to print nice pads like those:
Then just insert them in your case holes and all is done.
Protip: If you print it from FLEX plastic you will get noise absorbers for free (but I didn't try to print it from it).
