Motorola XPR 3500e KnobGuard

This model guards the knobs on a Motorola XPR 3500e so the volume and channel aren't accidentally changed. I finally got fed up with the volume and channel settings of the radio being changed by rubbing against my clothes as I walked around the plant. This part slides over the antenna and protects the volume and channel selector knobs. I prefer to print it in TPU, but it works fine if printed in PLA. It will grip the antenna and stay on even if you wear the radio upside down on your vest, but is easy to slide off if you need to change the radio's settings.
