I like your idea to replace rods with rails. Now I have a prusa i3 DIY clone and I'm seriously thinking to realize an Hypercube printer (I love the tools change idea even if I don't like bowden solutions).
I just want to ask you one thing...maybe two:
1) how you keep X rail fixed? I see XY intersect don't have stoppers so rails could escape..or not?
2) When you say your build is for a 300x300x300 I think you talk about 'Min. Build Volume / Travel
' field in xls Scott's file with such configuration is there enough space for not bowden changeable carriages?
