This is a remix of a human tooth model that contained pipes in the roots for money rolls (https://www.thingiverse.com/thing:6145572). The one issue was that it wasn't anatomically correct and, as a dentist, I had to tinker around with it before it was suitable as a gift for a colleague.

It's more low-poly looking now and the anatomy is much more faithful for an upper right permanent molar (it's based on tooth #3). I paused the print at 50% and inserted the money rolls in the roots and then continued the print.

I did notice that if I "repair" the model, it fills the interior with infill and you lose the hollow roots in which to put the cash. Maybe someone smarter than me can fix that issue.
