Knobs for Tektronix TDS 200, 210, 220

I've had a TDS 220 oscilloscope in my lab for years, but all the knobs were broken, or worse, repaired with glue. Finally, I no longer had the power button: I used a pencil to turn it on! I said enough is enough, and now it's back to new. It does its job very well and will continue to do so for years to come. Thanks to Bambulab!I started with a design I found online and modified it, especially the power button, which was not similar to the original. I wanted to replicate the buttons exactly as they were originally. As for the color, I'm still thinking about it. I think I'll leave them in the original color of the BambuLab spool I used (PLA-matte).
