Classic Hourglass frame

pinshape

The poles stand at 21 cm in length and the bases measure 9 cm square. Designed for an 18 cm gap between the inside surfaces of the bases, the poles are crafted with precision. The recessed circles begin at 7cm in diameter, tapering to 4 cm at a depth of 1cm. Built to last, the frame pictured was created using Laywood, necessitating 4mm perimeter and 40% infill settings for the poles, but standard settings (1mm perimeter and 20% infill) were used for the bases. This accounted for approximately 60 grams per object, whether a pole or a base, when working with LayWood. To achieve the tree ring look of real wood, I employed variable temperatures. It's worth noting that higher temperatures tend to weaken the structure. Before attempting to print the frame with Laywood, sizing and stress checks were conducted using HIPS. This allows you to use inexpensive HIPS with standard settings (although it won't replicate the wood-like appearance). For shock absorption between the hourglass itself and the bases, I used common fabric-like styrofoam packing cut into circles. The hourglass was purchased at a local Pottery Barn store, although I'm unable to provide a link to the specific model we acquired. This frame was printed on a Lulzbot Taz5 3D printer.
