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).
