My shul has beautiful furniture from Kibbutz Lavi where every seat has a shtender that folds down when you're seated, folds up when you're standing and...Show more can also be folded out as a little table for putting on / taking off your tefillin.
I've always wished that the shtender was a little bit taller, so I made the Exshtender for my own use to accomplish just that.
Some members of my shul expressed interest in having one as well.
As there may be a larger audience for the Exshtender, I'm placing it here. Now, you can get it without travelling to my shul.
Note: I recommend selecting Polyesters/PETG for the material -- it's the only one that I've tested.
