Customisable filament guide for 2020 extrusion.

thingiverse

Having designed several different filament guides, each with its own advantages and disadvantages, without finding one that perfectly met my needs, I decided to create my own custom version. The design wraps securely around a printer frame made from sturdy 2020 aluminum extrusion and is specifically designed for use with the filament spool feeding from the rear - though this becomes less critical as the arm length increases. Most elements are adjustable, except for the 2020 dimensions, allowing sufficient flexibility to achieve satisfactory results regardless of the parameter values supplied. This project remains a work in progress, and a detailed parameter guide will be available once I've completed it. In the meantime, you can still experiment by testing how the parameters affect the model through trial and error.
