Hourglass Bottle Cup

This a remix of a simple bottle cup design. It has a 5mm gap in the middle so that it can be used as an hourglass if connected with two bottles. It fits great on coca-cola bottles and those which have similar lids. Print at 0.2 layer heigt, because this model has a sacrificial layer, which is (of course) 0.2mm thick.

In case the model is upside down, turn it around in yuor slicing software so that the hole is facing up.
