About this 3D model

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.
