Motorola VHF radio channel knob guard

A small knob guard designed for handheld Motorola VHF radios / DMRs, probably fits multiple different models. Prevents the channel knob from unintentionally moving and changing channel by mistake, which sometimes happens too easily when the radio brushes against something etc.

The smooth loop slides on the radio's Antenna, while the knurled smaller loop is pressed around the channel knob to prevent it from turning.

Most likely you want to print this from TPU (I used TPU-95A) but it may also work with some other materials that have some flex such as PETG or PP. 

When printing with TPU, recommend using 100% infill.

Should print easily with no supports.
