The Floating glass
I Recently saw this strange looking glass:
and I saw people wondering if the 3D model exists, if it's food-safe, if it floats and if it's available in different shapes and volumes.
Yes, the 3D model does exist, it floats thanks to nuts thats you can screw on the glass, and yes it's available in different shapes.
• 155 mL, suitable for Wine
• 245 mL, suitable for Soda or Beer.
I'm using Metric units, so it's an ISO M8 thread. It's not considered food safe to drink in PLA, PETG, ABS coming from a 3D printer. Though, as long as you clean your glass, there is no worries drinking into it. The Wine is way more dangerous that the glass itself. (dishwasher is not recommended). You can add a resin coating to your glass to protect it.The main problem you might encounter is a leaking glass, but it depends on your printing technique.
200µm; 70mm/s; 3 perimeters
These are suggested printing settings.
I designed this glass thanks to Solidworks. the steps shown here are just a way to do it. i admit there are a lot of other ways to achieve.
I Started creating a sketch, with splines to get the global glass shape
With the revolve tool i created a basic shell shape
I then added a M8 thread
With a plane intersecting the shell i calculated the internal volume thanks to the intersect tool. Therefore i could adjust the shape of the glass to change its volume.
