(Updated! Base now rests into base and top pieces!) This is my first upload to this site, it is a small hourglass I made based off of a model I made in 3DS MAX. This comes with both STL and Inventor Part & Assembly files for your preference. I have not printed this yet but all assembly attachments fit. The rods lay inside of the base and top, and do not screw in. If you want to make it a permanent fixture use some sort of glue or epoxy of your choice. Recommended transparent filament for the glass piece!
