About this 3D model

I have a problem - it's difficult to demonstrate a 3D printer to your guests - you show them the printer, send a small print, and .... it will be ready after they leave. So I designed this model with the explicit purpose of being able to completely pint it before everyone get's bored and moves on. This model takes 9 minutes according to Cura's estimate, in reality, on my printer, it takes 12 minutes (not including warmup) This model is tiny, the features of this model are probably just about the smallest you can print with a 0.4mm nozzle
