Coffee anyone?! Why use cheap disposable cups when you can make your own fragile ones at far greater cost? :D
But seriously, herein lie models for both solid coffee cup organisers/vases, and for vase-mode experiments. The solid models might actually be useful, but the vase mode stuff is so much fun!
The solid models are self-explanatory - the grey cup in the photos is one of these. Easy prints, and they look like coffee cups. These are probably the ones you want, if you want the objects to be useful. See the printing details below for more details.
And then we have.... Vase Mode!
So, these are a little tricky to print in vase mode, for at least two reasons:
Firstly, vase mode works best with gradual shape changes. Abrupt profile changes will cause weak spots or failures during printing - overhangs are a disaster. These models have been designed to minimise the profile change, but there's only so far you can do that before the thing no longer looks like a disposable coffee cup, so it's a compromise. Anyway, prepare for potential problems where the base becomes the body, and where the body becomes the lip!
Secondly, filament changes for colour shifting is a daring exercise. Because vase mode involves a single extruded line, any underextrusion is a big problem. So, when you're changing filaments, you need the new filament ready to begin extruding right away when the print resumes. If that doesn't happen, you get a big gap. So, prepare for weak points at colour changes!
That said, such printing disasters are great fun, and very much worthwhile. I printed with a 4mm nozzle, but it might well be better with a bigger one. Also, maybe spraying a clear coat of something over the things afterwards might add some strength, too.
Have fun!
Solid models:
Easy prints, nothing tricky here! The filenames with "solid... full model" are the ones you want. Change colours at 5mm and 95mm if you want the full disposable cup look.
Dual solid models:
These models have the base and rim separated from the body, to make it easy to print on dual-material machines. If you have one of these, you probably already know how to do this. There's nothing difficult about the design itself, though.
And now... VASE MODE!
Well, spiralize outer contour, in Cura language. So, this is a bit of a tricky one, for at least two reasons - see the description above for details! Have fun!
