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 for 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!

Modeled in NX6, rendered and animated in Modo, .stl files cleaned up in Blender, exploded view created with Rhino and Illustrator, sketches with Sharpie.

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.
