Weighted Dice

With this die, you will have a higher chance of rolling a 1. For it to work, you must pause the print at layer 110 (assuming .2mm layer height). Once the print is paused, fill the larger chamber (one by the six side) with BBs, and then resume printing.

To pause the print at a certain height/layer in Cura: Extension(alt+x)>Post Processing>Modify G-Code

I have included the STEP file so that you can customize the die to your liking.
