MartiniGlass

thingiverse

Update I have included 2 additional STL files in this group so they all would be in the same place. Martiniglass4 is the small, tall/thin one, and martiniglass 5 is the largest one. To print the whole set it would probably be wise to rescale the larger ones because the native scale is not the same for all 5. ----------------------------- Here are 3 different shapes I developed essentially by accident. I started with a shape based on a sine curve, but that didn't produce anything acceptable, so I switched to a conic curve to try something simpler. It wasn't long before the profile curve for martiniglass1 appeared, so I used it as the basis for a circular sweep which then resulted in the martinitglass1 STL file. When martiniglass1 was finished I thought it might be nice to make a couple of companion pieces for it. The conic curve method was not nearly complex enough for anything other than that particular shape, so I reverted to one of my standard methods of using a stacked set of closed curves as control curves for a Loft surface. Martiniglass2 is the first of these; it uses circles as the control curves and I made it look sort of like a wineglass, but I gave it a thicker stem for strength. The largest one uses 11-sided polygons with filleted corners for it's control curves. It is the simplest shape of all, and serves as a contrast for the other 2. Of course none of these prints can actually be used to hold martinis, or any other liquid, because PLA is hygroscopic (it absorbs moisture) and in general 3D prints are not watertight due to tine gaps between layers. martiniglass1 printed in 13 1/2 hours, martiniglass2 took a bit less than 33 1/2 hours, and martiniglass3 printed in 19 3/4 hours. All used a print speed of 100 mm/sec. and a layer height of 0.200 mm.
