(tr)uSDX Tuning Knobs

thingiverse

The standard tuning knob for the (tr)uSDX is tall, skinny, and not so nice to use. If you cut about 4-5mm off of your encoder post, bringing the end of it down to no more than 11mm above the front panel of the radio case, you can print one of these knobs and use it instead. The 25mm knob does not extend past the edge of the front plate and looks slightly better on the radio, and the 28mm knob provides better usability. Both knobs are about 12.5mm in height and include a finger indent or dimple to allow easy spinning of the knob with one finger or thumb. Each simply presses into place, relying on friction to hold it in place.
