I had dream not too long ago that I printed some replacement teeth for myself but they were too large and were really rough because I had the layer height set really large and the teeth kept breaking because the layer adhesion was bad and they were noticeably different color from my other teeth and ... am I the only one with that dream? Weird. :-) 

Haha thats funny because recently I made a whole bag of tooth sized molars from natural colored ABS, and also added a drop of Gold paint on top for realism! I can easily print like 36 at a time and they came out great!  And besides what is funnier than a bag of gold-filled molars to terrorize everyone with?
