Number Dials/Revolving Counter

thingiverse

I wanted to make a dial to keep track of hit points for some big monsters. I figured the HPs would be over 100, so I made three dials. I put these together in Tinkercad. There are nubbins on one side and indentations on the other so that the dials will rotate and "stick." The idea was that I would pass a rubberband through the three dials and then secure them on either end behind the disks with the arrows. The little "batarang" bits would hold onto the rubberband and provide tension. I can't get it to print, however, without it sticking horribly to the raft. It prints fine, but I haven't been able to assemble and test one.
