Customisable, scale-to-print urn.

<p>The hexagonal decorations are based on a mathematically defined shape I named "DecoHex". By removing facets in the base DecoHex I created over 235 variations applicable for vases, vessels, bowls, and for an urn.</p><p>About the design and your end result…</p><ul><li>The urn is double-walled to protect the precious ashes.</li><li>Two base urns with different feet.</li><li>Four diferent lids. Two are recessed to hold personal items. Or a small candle if placed in isolating material and a container such as a metal tin or a glass holder. Be sure nothing touches the filament. When in doubt always test first. It's best to glue the lid permanently.</li><li>The top of the lids are blank to place texts and bitmapped or rasterized images.</li><li>Fusion360 design included.</li><li>Print shown is made with Prusament Galaxy Black. It looks gorgeous. However, take notice where the urn will stand, choose your filament accordingly.</li></ul><p>This is a parametric design ypou can to scale up or down to hold less or more ashes. At 100% this urn holds up to 1.9 litres or 116 cubic inches of ashes. In the funeral business sized “Medium” for human remains weighing less than 40kg or 88.2lbs. Body weight X <i>0.035 = weight of ashes. Body weight X 0,0475 = volume of ashes. Or 1 kg equals 0,05 cl or 1 lbs for every 1 cubic inch.</i></p><p>To determine the right percentage keep the following in mind…</p><ul><li>Iterate the desired volume with the “Volume-scaler”. It is attached as a model file and in the Fusion 360 document. Scale up or down to measure the volume. When the right percentage is found you can apply found percentage to the urn and cover. Tip: iterate for a height that equals a multiple of the desired layer height.</li><li>Don't calculate too precise or too economical. Prevent the urn of not holding all of the ashes. During cremation other items may be burnt and collected. This may be the transfer box inside the coffin, medical safety materials, clothing and so on. Tip: ask the undertaker/mortician for the weight and if any additional material was burnt as well.</li></ul><p>Print instructions…</p><ul><li>Nozzle diameter: 0.40, 0.60 or 0.80.</li><li>Layer height: 200µ.</li><li>Perimeters: 3 or more to manage overhang.</li><li>Best to print the bottom as a solid: 12 x 200μ.</li><li>Quality to speed tested with Colorfabb nGen, Aprintapro Pure, Prusament PLA and Fillamentum Crystal Clear. Good results can be expected with speeds up to 50 mm/s.</li></ul><p>Cheerio!<br>David</p>
