Sugar Rush Doughnut Box!

Anyone for doughnuts?!  Add some cheerfulness to your day with these sprinkle-topped icing-laden toroidal extravaganzas!  It works very nicely with magnets, but pegs are provided as an alternative - more on that below!
So, the technical stuff!  This was an exercise in seeing if I could make an easily-printed lid with asymmetric curves that would be printable without needing supports,   and which would still just show a nice curvy line on the outside where it meets the base.  Flip the lid over and you'll see how that was achieved - basically lots of tapering inwards from the outside of the curve. 
Of course, the fact that the two parts match up cleanly also means it would be difficult to just pull the lid off, so there's a little indent on the inside of the base to help matters.  The magnet/peg spots on the inside are also asymmetrically spaced, for a specific reason - it makes it much easier to work out which way the lid goes on! 
Oh, and those sprinkles are intended to be glued in, but if you're feeling adventurous you could scale them up slightly for a friction fit!


To Magnet or Not To Magnet
This thing works beautifully with eight 6x3mm magnets (the same size all the recent magnetic options use).  
However, magnets aren't necessarily for everyone, so there's an alternative included - a stepped peg that can be glued into the magnet points on the base, and will stop the lid sliding off.
You don't *need* either, but it's definitely better with one of those options in place!



Printing Tips and Thoughts on Multimaterial
Sugar Rush Doughnut Box is designed for straightforward printing!  No supports required.  However, the top of the icing and the sprinkle are curved, so you'll probably want to either print with a small layer height or us a variable layer height (if your slicer supports it) to make the curved tops as neat as possible.
All the parts print right-side-up, like so:

So, this is a colourful design (potentially) and the obvious thought is that multimaterial printing could come into play here!  However, this is one of those designs where that would simply add material consumption and increase print failure risk without actually gaining anything in the end result (compared to gluing the sprinkles in).
That said, if anyone's really, really excited to print this all in one multimaterial go, let me know and I'll do up a multimaterial version with all the parts in the right places :)

Print Dimensions
Base occupies 130 x 130 x 34mm on the print bed
Icing Lid occupies 118 x 118 x 13mm on the print bed
Sprinkle and Peg are tiny :)

Further Thoughts
Huge thanks to Filament Stories (https://www.instagram.com/filamentstories) for endless testing and feedback on this model, which improved it in countless ways!
Well, the only downside to these things is that they're making me hungry, and I'm pretty sure they aren't edible, at least not using the printers I have!
Happy printing!
