I recently got the Chtulhu: Death May Die boardgame, and many of the monsters in there use 50 mm bases. So, I figured that I'd better make a 50 mm HP Dial! This uses the same basic parts as my 25 mm base, just spaced out for the larger base. Because it's larger, I was able to make it go from 1-20, which is good, because larger creatures usually have more HP! In my efforts to make the numbers legible, I made them as large as possible, which means that the wider numbers (basically, 10+) are pretty tight in the window. I think they work though =)
