(Yet another) Square Card Reader Holder
thingiverse
Not satisfied with the ones I saw out there, I designed my own Square card-reader holder for my iPad. It holds it nice and rigid; no swiveling. Probably won't fit newer iPads (e.g., "air") as well due to the different thickness, etc. (I should probably figure out how to use the customizer :) Instructions It is designed to print on-edge; I would recommend printing with a brim, since the footprint on the print plate will be small.
