Modified Lego Ring

This ring is a modified version of: http://www.thingiverse.com/thing:243202 All I did was cut the corners out where the Lego block sits. Most printers will make that corner kind of sloppy (which is a problem with real Legos that have sharp corners), and a closed corner also makes it a real pain to adjust with a small file. Visually, you can barely detect they're there.
