A pair of plant stands from a friend’s collection ended up in Mary’s care and cried out for feet to keep their welded steel wire legs from scratching the floor:
Admittedly, it’s not the prettiest stand you can imagine, but the sentimental value outweighs all other considerations.
The feet are shrink-wrapped around the legs with enough curviness to look good:
With a drain hole in the bottom to prevent water from rusting the wires any more than they already are:
I briefly considered a flat bottom at the proper angle to sit on the floor, but came to my senses; it would never sit at the proper angle.
The end results snapped into place:
Of course the other stand, at first glance identical to the one above, has a different wire size and slightly different geometry, which I only discovered after printing another trio of feet. Changing the appropriate constants in the OpenSCAD program and waiting an hour produced a better outcome:
Living in the future is good, all things considered.
