Tektronix Zoom Knob

thingiverse

Quick mock-up of a Tektronix zoom knob that should work on the MDO/ MSO/ DPO 3000, 4000 and 5000 series. These knobs are relatively easy to pull out or break off, which is why I've seen several college labs where students have done just that. This design doesn't improve upon their strength or ease of removal, but it can be a more cost-effective option if you only need to replace one or two knobs at a time. I've included the SketchUp file so feel free to edit the model as needed. Adding a better grip could be beneficial; I simply followed the default Tektronix knob design pattern.
