Linear rails for the Printable Unicorn

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! ;)
