PrintrBot Spool Coaster Bearing Fastener

I picked up this PrintrBot Spool Coaster (http://printrbot.com/shop/spool-coaster/), and while putting it together, promptly broke one of the fasteners that holds the bearings.

So, I designed a replacement on Google Sketchup and printed one on my PrintrBot Simple. It works perfectly now. Thought this might be useful for others too.
