About this 3D model

Join to my Tribe and get every month models to your collection. JOIN NOW!!! Today I wanna share with you my latest design, An hourglass (or sandglass, sand timer, sand clock or egg timer) is a device used to measure the passage of time. It comprises two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance (historically sand) from the upper bulb to the lower one. Typically, the upper and lower bulbs are symmetric so that the hourglass will measure the same duration regardless of orientation. The specific duration of time a given hourglass measures is determined by factors including the quantity and coarseness of the particulate matter, the bulb size, and the neck width. My Hourglass has 2 screw caps on top and bottom. Please use fine sand without big grains of sand. I love this project and hope you will love also.
