This is my variation on the Rostock printer. It is pretty much Johann's original design with the following changes:

1) Braid fishing line instead of belts for main axis drives,
2) Threaded drive pulleys to prevent braid tangles,
3) Use of planetary gear box on extruder,
4) Custom Bowden hot-end holder.

The main reason for the braid in place of the drive belts was that I was finding it hard to source GT2 timing belts/pulleys, and braid fishing line was a cheap alternate that a friend suggested I try. I was a bit skeptical that the braid would work, but so far it has proven to be most effective.
