Vial Pincher for single-dose eye drop vials

I made this simple tool for my mother, who needs to take eyedrops that are provided in “single dose vials”. The plastic of these vials can be rather stiff, and she has weak hands. Hence, a simple pincher, to increase the grip strength on the vial.

I printed this in clear PETG. Any colour is ok, but I recommend PETG over PLA (as PETG is more flexible).

The design is in OpenSCAD. The design file is also among the downloadable files.
