Dotted dice - d6, d0-5, and d9-9

These are good old dice with pips (dots) on them. I include three versions:

• d1-6_pips.stl is a standard d6 with the pips on each face numbered to match (i.e. 5 pips for the 5-face).
• d0-5_pips.stl starts counting at 0 instead of 1. The pips are also numbered to match.
• d9-9_customisable.stl (pictured above) has 9 pips on every face. This allows you to paint each face to make whatever arrangement you want.

You may want the d0-5 for randomly selecting items from a list, for example, because you could roll two or more dice and still have a chance of rolling 1.

I have tested multiple prints of both of these designs using the simplified chi-square test described by 'Delta', and found them to be fair (or more accurately, probably-not-unfair) at α = 0.05 and 120 rolls each.
