Radio knob covers

My ham shack tends to be dark, making it difficult at times to see the radio knobs out of my peripheral vision. I used tinkercad in minutes to put together a know that can be printed from TPU to slip over the radio dial, making it more visible. I used gray TPU to keep the black radio theme. There are 3 different sizes I came up with to get it right. The 15mm fits the tuning dials on my Icom 2730a well while the 16mm fits all of the dials on the FT-991a perfectly. Very simple print and design but it solved my issues!
