Have a Tektronix TAS 220? Have those long knobs for "Variable" and "Sweep Variable" broken for you, too? Good news: now you can just print a new one, and your semi-vintage oscilloscope can live on for a few more years!

There are two knobs attached:

• A longer knob designed to replace any channel's "Variable" knob named "variable" in the attached files.

• A shorter knob designed to replace the "Sweep Variable" knob named "variable sweep" in the attached files. Print Settings

Notes:

If you're only printing one or two knobs at a time, your layer will probably not have enough time to cool before the next layer is being printed, and you may end up with just a blob of plastic. I printed mine using ProtoParadigm Light Stone Gray PLA filament with a minimum layer time of 5 seconds to allow the layer to cool before it proceeds to the next.
