For the few of you who have not seen this video yet of the Twin Rail Mobius Pendant it is worth taking a mind bending look at the the ball bearings as they chase themselves to infinity.  The video has already racked up over 1.7 million views and growing.

Making a video of your 3d printed design is a perfect way to showcase your item, let people see it from different angles, get an idea of scale and is especially useful if it involves moving parts.  Posting on YouTube can really help to expose your design and you can embed your video into your product page.
