Cupcake CNC transformer

So Make: recently introduced a contest to give away a Cupcake CNC FDM machine kit, and I came up with this entry…

What’s cooler than transformers? A Cupcake CNC transformer with a Bre head? This is a fully articulated assembly that transforms from a Cupcake CNC to a Bre-bot.
I started with a snap-together design (see the attached concept sketches) but migrated to a bolt-together kit or various reasons. The final design allows for fine adjustment of the joint tension so the transformer can stand in any position but still be movable, positionable, transformable!

Buildable in two Cupcake CNC builds (see screenshots), this transformer is assembled with commonly available 6-32 (3/4″ long) flat head machine screws and corresponding lock nuts. NOTE: may be substituted with M3.5 x 20 screws and nuts. 15 sets of screws and nuts are required.

UPDATE: Thanks a bunch to Frank for printing one!

    @ cbase_3D Agreed. But I will try anyway:
    Crystal clear awesomeness! Five stars. A++. 21/20. Complete digg. Hors concours. Bravo.
    It’s as good as a three wolfs t-shirt.
    It’s like watching 3 episodes of… of… Battlestar Galactica with a bucket of cream puffs and have good sex right after. Fracking good stuff!

    Very very cool Joel. The only thing I don’t like (as with many things) is that I didn’t come up with it first. Good luck in the contest!
