Found this interesting comment. (i guess I wasn't wrong about that tripod style design).

Quote: "flexible shaft? why? Printer can handle Dremel without problems. Precision is suck, due to bad Geeetech 3D printer design."

I have a long flexible shaft too. Perhaps it could be possible with the ally getech? Though I'm still worried that the "precision is suck".

Thoughts?
