Weighted Encoder Knobs

These knobs fit the standard 8mm encoder D shaft and provide some additional weight to improve the overall knob feel. I made these for amateur radio projects but they should be generally useable.

All these files are designed to use 4.5mm airsoft shot to provide the additional weight. "Hole" models are designed to have the shot friction fit into the holes. I used a tool to force the shot to the front before applying further layers. Versions of the "channel" type provide more space for shot
