Hello Hello Everyone.
When I puchased my Ultrasaber I was gettin the rundown aobut it and the tech mentioned avoiding pressing the speaker.
I made a quick comment about 3D printing something and finally decided to act on.

It's a simple design that just sits around the speaker and you can just push with the palm of your hand without worry.
I've used mine a few times on my Apprentice V5 and Emperors Hand and so far so Very Good.
