Description

A shot glass shaped like everyone's favorite hydroxyl group.

Instructions

Do not drink from a 3D printed glass unless you are absolutely sure the plastic you are using is safe and will not leach into, or react with your drink (I only filled it with water for the picture, then dumped it out after).

This STL is full of holes and reports many many errors...

Hey ScribbleJ,

Thank's for the picture of it printed :). I hope it didn't give you too much trouble.

I got the same result in RepG, but as you can see it printed fine anyway... I'm not sure where the issue is as it's a direct export from solidworks... I also took the STL into meshlab and couldn't find any probl
ems. I imported it back into solidworks, and couldn't find any there either. Blender is showing that the outer edges of the H are the problem areas... but that's the simplest part of the STL and I don't visually see any problems... do you have any idea why this would happen?

It printed just fine anyhow! Obviously, I'm still in the process of tuning my Prusa. This is my first non-calibration-block print. :)

PLA is non-toxic and breaks down into harmless lactic acid. I doubt it would react well to alcohol but I can't imagine the result would be bad for you.

Although I guess there's no telling what dyes might be made out of. Natural PLA should be safe then.

Added the 'pun' tag to this wonderful thing. :-)

Your glass looks like it's made from ABS, this is what's used to make Lego which has uneventfully passed through millions of children and pets.

You can seal printed glasses by rubbing them with wax. Scotch guard might also work; anyone know if it's soluble and toxic?

It actually holds water very well, without any leaks, which I was surprised about because printed objects rarely do that. My issue is less with the type of plastic itself, and more with how it will react in regards to alcohol. I placed a piece of raft in some vodka overnight as a test, and the vodka had a slight red tint in the morning, though that was an unwashed piece of plastic, I'm not sure how a thoroughly cleaned glass would fare.

Even then, people use a variety of plastics from a variety of sources for their printers and I just wanted to make sure everyone looks into it before consuming anything :).
