After looking at the Star Wars Legion trooper bases I thought they looked perfect for lego minifigures as well. I designed two types of bases, one that is partially hollow and closely resembles the SW Legion bases, and another that is solid all the way through.
Please note that the studs are oversized by 0.1mm to ensure a tight fit. Do not force your minufigure onto the studs if they don't fit since this can cause the minifigures legs to crack.
The hollow version will need supports, the solid version will not.
