3D Printed Planetary Gear Bearing

I found this on thingiverse the other day.  I wanted to see how it would print on the Behemoth.  The only way it can be made is on a 3d printer.  It can’t be assembled or dissambled (at least without breaking it).  It printed great and it was very easy to break the gears free and start rotating it.  I ran it in a drill a little bit and it loosened up very nicely.  I’m not sure how long they will last but I intend to use them in the smaller 1 pound spools.
