Hourglass

This is a small hourglass (7cm tall). I printed the hourglass itself with transparent PLA, although it is really translucent.
Depending on the sand or other material you use, it reads about 10 seconds.
In the end I did not use the printed columns, but some wooden kitchen sticks.
The base and top have a good fit with the hourglass, but I used hotglue to fix them and the columns as well
