Akimbo is a redesign of the RepRap Mendel, designed with increased build area, dual extrusion, easier assembly and increased rigidity in mind.
Things to like about it:
1) If you opt for a single extruder, it's easier to attain the full 200x200 build area, than on previous designs.
2) Taller build height - if you limit X travel at the top, the extruder can slip between the top horizontal rods, increasing your build height to 180mm.
3) Desigend with a second extruder in mind. Adding a second extruder comes with minimal reduction in build area.
4) Easier assembly - Akimbo uses a hybrid approach to it's linear motion, with a one rail on each axis fully constrained, and the other constrained only against rotation, giving smooth motion to printers which don't have perfect rod alignment.
4) Increased rigidity - The geometry of the frame is modified to increase triangulation, and all rods are rigidly clamped (no press fit parts).
Things that still need work:
1) While the mechanical design for dual extrusion is finished, it still needs both electrical and firmware support.
2) BOM and Assembly instructions need to be created.
