rigged dice

a parametric rigged dice. you can choose the face that will most likely show up, the amount of crookery to put inside, and about all other parameters you may think about.
*edit*
I finally had a chance to have one of these printed before I received my printer, and i learnt a couple thinks :
*The round corners (value was set to 0.8) are pretty challenging to print, too much overhang. Try higher values
* 0.1 is too small. Try dot depths of at least 0.5mm
*infill must be set to 100, at 20% there is not enough weight to obtain an observable shift in the odds of getting the rigged face up.
