Glass Tom Case using 5mm Acrylic (Q58620)

I was looking for Acrylic Draw Design for standard 5mm thick acrylic. I also like to include some latest improvement from evanevery(http://www.thingiverse.com/thing:13261) such as stress relief and other holes for additional fan mount. However, evanevery's design is made for 5.5mm~5.9mm thickness board which won't work for standard 5mm board. So, This drawing is designing for board thickness tolerance in 4.6mm~5.2mm. All t-slot also have stress relief to prevent cracking under stress. I try to pack all small parts into the window to save the board usage.
