This is an episode of "Will It Print?" :)

I designed this almost 13 months ago, but back then, I couldn't manage to successfully print on my MakerBot. So I forgot about it. Today, I found the files on my hard disk and tried it again...

Surprise: It prints! (sort of)

There's some serious oozing going on (see pictures). Also Skeinforge moans and groans when slicing this one...

What surprised me most: after breaking away the support parts and cleaning it up, it turns out that the three rings indeed interlock. There's no way to separate them without breaking at least one of them...

This thing is designed with all necessary support parts as part of the object. After printing, you want to cut and break away most of the printed material (see photos).
