That print was super impressive...

If I were you (and I'm not) and had that printer and idea (which I dont) and had the guts to print that and walk away (which I dont) here is what I would have done...

instead of being flat, I would have given it a wavy profile (like cardboard innards) instead of a straight profile. would be much more rigid also.

I love it!!!! I am rethinking this printer now... wavering this or the prusa style from folgertec.......
