clean pull door handle attachment

Door handle attachment, which allows user to turn the handle and pull the door open without touching the handle with (bare) hands - all in the name of slowing the spread of covid19.
This model attaches to the shaft, which connects the handle to the door. One two-part model works for cylindrical shafts 1" in diameter - popular size in the US. The other model works with hose clamps and is more flexible about the size and shape of the shaft.
Caution: a) this model doesn't work with circular door knobs; b) if this attachment interferes with regular cleaning of the door handle, it might do more harm than good.
The campaign to make door handles hands-free was started by i.Materialize.
