A lid for the bucky bowl.

It makes it look a bit like a cubist capsicum.

Update - the new supported version is buckybowl-lid-2

As scaled here it is very tight - you may want to reduce it a percent or so.
You might want to print the first dozen layers as a size test before attempting the complete part.
Be prepared to do some fitting afterward.
The model and printer will have slight errors so it may fit better is one orientation.
I had trouble with the bridging and added extra support structures.
The latest version is untested (later - not good).
After running some tests http://www.thingiverse.com/thing:304172
I changed the support structure to 3 walls running in the Y direction.
Your mileage may vary but this bridged perfectly for me.
I also slowed my bridging speed from 60mm/sec to 10mm/sec

I've also uploaded and unsupported version.
