Zoji ZT0375 oscilloscope / multimeter holder for Gridfinity

I made a Gridfinity-based holder for the popular and cheap Zoji oscilloscope.  A few other accessories are supplied in the 3MF and FCStd files as well.

With magnets on both the holder and the base, the device stays firmly in place and is very much usable directly from the holder — push buttons do not cause it to move.

Note that the magnet holes in these parts are 6 mm, not 6.5!
