The enclosure isn’t designed for heavy objects. If the tracker you attach causes a wobble when you move your hands around it will likely mean your wrists appear to wobble on your character or avatar and you may also damage your Studio Gloves. While bracing the mount to the back of your hand may help, DO NOT ATTACH OBJECTS THAT CREATE SIGNIFICANT WOBBLE when attached to your Studio Glove as the wobble will tear your gloves.
We encourage the use of third party straps like those found at this link if you intend on performing particularly rigorous action with the Vive trackers in particular, or any other large tracker.
