About this 3D model

I wanted to play around with making funcitonal objects using vase mode to help quick prints. I created this to fit normal 3.5in x 2in business cards and a pen or pencil under 15mm in diameter. the warped look at the top was designed to keep the cards from falling out when stuffed in a desk. Spiralize the outer contour, at 0.2mm print height. 150mm/s print speed. 75mm/s upper and lower portions. prints in about 30 minutes. 0.5mm line width using a .4mm diameter extruder. (you can substitude higher material flow rate instead of the 0.5mm line width, but that would cause buldging in the base plate.)
