I needed more height out of the Nobsound (Douk audio) spring isolator to lay a piece of aluminum across for a desktop amp rack/shelf.
The spring isolator is made for turntables and audio equipment, and probably doesn't make a different sonically in this case, but it looks cool!
I also included a file for a TPU foot, but I haven't tested that yet!
I printed it from CF-PETG and PLA without issue. (I don't mention other materials as I did not need to try any other materials, but I am confident anything will work.)
The author marked this model as their own original creation.
