I agree; 2mm wall thickness is my default setting for shelling parts while keeping them strong.

The guideline I made, [Designing for the Form 1](http://formlabs.com/en/company/blog/2013/09/25/design-guidelines-for-the-form-1/ "Designing for the Form 1"), has wall thickness descriptions as such:

> \*\*WALL THICKNESS  
> \*\*  
> • Strong: 2 mm  
> • Flexible: 1 mm  
> • Delicate: 0.5 mm
