Anti-vibration feet for GEEETech i3 Pro B with 8mm acrylic frame

I was seeing a lot of vibration dampening feet, or people with foam under their printers, or other methods of silencing their printer.

I have taken the designs of bernbout and kb3lnn and combined them so that you can easily out vibration dampening feet under your GEEETech i3 Pro B without making modifications to it to actually mount something to them.

These feet together with the decoupler rings for the stepper make the printer very quiet.
