This is a fold up foot for a Tektronix Digital Storage Oscilloscope.
My DSO is a TDS2024, but i think this will fit the TDS2000 range, maybe even more.

If you have lost or broken a foot then print a replacement or two, or print a spare for when you do break one.

These are a squeeze fit, and then lock in the up or down position.

I printed my with 100% infill for max strength, but you can use less for more flex.

You may need to file the hinge pins, depending on how well the rounded pins print.

This was copied from the remaining good leg in SolidWorks. I have included the solidworks 2010 part file here in case i need to find it again.
