Summary
2 re-meshed phone holders that can be used by people with limited finger mobility. I cant remember which original models i used for the 2 holders, since I had to edit and remake them extensively.

The 'lip' must be dipped in boiling water for 15 seconds, and then shaped around the person's hand. See pictures.

If you use any-flat.stl... then you have to glue it to your existing phone holder. IE, in this case you dont have a iphone7 or galaxay note 8, but you still want to shape a holder.
