A fully parameterizable "stand" or "holder" for anything that will fit in a rectangular hole. I specifically used it to create a desktop stand for a cell phone, but as the pictures show, you could also use it to make a sugar packet holder or business card holder.

The size of the rectangular "hole", the wall thickness, the base size are all customizable via parameters. You can also decide if you want just the vertical corners rounded, or all (top/bottom) corners rounded.

The scad file also has a "test" mode that prints a 8mm high rectangular piece you can fit around your object to make sure it will fit into the "hole" once you print the full sized holder/stand.

Version 2: Includes a "viewing cutout" if you want to be able to see the screen of your cell phone.

If you just want a Motorola Backflip or Sony Xperia Mini cell phone holder, go ahead and slice and print the appropriate STL file. Otherwise, you'll need to use OpenSCAD to open the .scad file, edit the size of your holder/base/hole and optional viewing cutout and then generate your own STL file.
