Drop the weight into the dice when the hole has almost finished printing.

Use (e.g.) a ball bearing ball of 6mm diameter as weight.

Or set rl to the radius of the weight you want to use.

Set drl to zero if you just want a normal, heavier dice.

Set vrl to a different direction (+/- xaxis, +/- yaxis, +/- zaxis) to load the dice towards different numbers.

// load
rl=6/2;

drl=drl_max;// drl=0; // makes a simple weighted dice

// direction of the loading (zaxis->more 6´s,-zaxis-> more 1`s,etc)
vrl=-zaxis;
