For my daughter's birthday I designed these animals to attach on straws.
Despite my limited skills in painting the girls loved them ;o)
Be aware, that they are quite big - see more in the print settings section.
The models are STL files of SolidWorks assemblies. Thus, your slicer may interpret the single object as multiple objects, which may cause gaps between the individual shapes.
Great fun if the kids help paint them too.

The animals were designed "out of imagination" - that is. The only design constraint was the 5mm hole that match the straws I had.
Be aware, that the STL files are an assembly from SolidWorks exported as a STL file.
As mentioned in the description this may cause problems in your slicer.
I have only tried in Simplify3D - but I hope you might be able fix it in you own slicer - if you find any issues (do contact me, if you would like to share other approaches!).
So, here it goes:
1) Start by scaling and rotating the object (see image for my recommendations).
2) Select the Mesh menu item and click the 'Separate Connected Surfaces'
- this will split the model into several object, but they will "float" at their respective location as long as you don't move anything.
3) Select all items and create a Group
4) And, now your ready to print!
The size of the heads are therefore a little bit too big.
I scaled them down to 80% and drilled the hole with a 5mm drill - do test if the cup will tip if it's empty.
Also, make sure to rotate the animal so, that the hole for the straw is vertical.
Print with 0.16mm layer height (or less), support and a brim.
