Hourglass

The world's first robust hourglass 3D-printed from PVB. It uses smoothed PVB for the “glass” and ultra silk PLA for the connector and decorations. The unique connector design eliminates the need for glue or other material and still provides a very stable hourglass that can be easily disassembled at any time.
