The more I look at this design, with the fixed hot-end, the more I admire it.
You could add 2 or 3 extruders without any strain on the effector platform, and no fiddling with bowden retraction issues.
Or you could even make a revolving turret type of thing with different types of extruders; i.e., 3mm filament, 1.75mm filament, chocolate frosting...
Perhaps, if it was a bit larger, you could squeeze the electronics in the space under the print bed when it does it's little dance at 0,0,0...
And an elliptical print bed...yeah, that's the ticket!
