From Quadcopter to a Robotic Arm - Mike's been busy!

Update from Mike:

So things have been getting crazy and printers have been flying around the world faster than santa. but I managed to squeeze some time in to some side projects
 
The quadcopter is still in the works, and while I figure out a few ideas of the direction I want to go with it and wait for some parts to arrive from my friends at autobotix.ca im shifting gears a bit to bring you this side side project
 
here at thingiverse: http://www.thingiverse.com/thing:1015238  I found this 3d printable robotic arm, and as luck would have it a few months ago I bought 50 or so of the same servos used in this arm.
So while pondering the quad I printed the parts on my ORD Solutions MH3000 printer, and began assembly
 
I don’t yet have pictures of my build but will get them out soon. With the build process underway, a few of the parts were tricky to print and needed to be run in multiple part batches because the design has low layer times at the top which often creates a situation where too much heat is dumped into a small area causing deformation of the part.
 
There are multiple strategies to address this issue, from slowing the print down when a layer takes less time to complete, printing multiples of the same part so that one can cool while the others are printing, or adding cooling fans.  I’ll post some examples later.
 
So watch for my printed examples of this arm and some build process and my quad project, check out the thingiverse link if you want to print this arm or the instructable http://www.instructables.com/id/EEZYbotARM/ for details from the creator of this item.
