Linear rails for the Printable Unicorn (Q60834)

A while back I printed a copy of the Printable unicorn then sat around scratching my head about what to use as a linear rail. A while later I was pulling apart an old DVD drive when I found two 2.9mm rods. Armed with my trusty digital calipers and pro desktop, I reverse engineered the print head of the printable unicorn with two arms extending backwards with two verticle guide holes, then designed two side brackets to hold the rails. I used melted ABS (with auto paint thinners) to glue the side rails to the body of the unicorn and then assembled it. When I'm done I will cut off the rails so that they don't extend past the top of the side rails! Now I just have to get it working! ;) PS: Sorry about the size of the .avi, I'm just recovering from a catastrophic SSD failure and I haven’t got around to installing my file conversion software!
