Kaiser KA9040 knobs

Replacement Knobs for the Kaiser KA9040

The channel selector on my old Kaiser CB Radio broke, so I designed a replacement. I didn't like the other look of the 3D-printed selector when in use with the original potentiometer knobs so I also designed these. 

Perhaps someone else still uses one of these old radios and has a need for replacement knobs. 

You may want to experiment with the print orientation. I landed on printing the channel selector standing on the narrow part using supports.

For the potentiometer knobs i used a drop of nail polish in the indicator groove to make it stand out.
