Product Description
Having difficulty keeping consistent traction with the string drive on my Printrbot Simple, I set out to design a more positive drive. Design parameters were: - Timing belt drive - "Bolt on" solution, no modification of machine required - Ability to revert back to string drive if necessary I made this version available to assist those who were having difficulty printing themselves.
