Printrbot Simple Metal Filament Tube Guide
thingiverse
I created a remix of the filament guide made by polysign and modified it entirely to match my printer's dimensions as well as accommodate my 4mm OD teflon tube. Printing this guide requires supports, however I am still unable to achieve a smooth finish for the overhang tube since it is too small to receive proper support structures. Fortunately, I have also included an alternative version of the model, which I dubbed the "blocky" edition, lacking the overhang cylinder that necessitates support; unfortunately this design lacks the sleek appearance of its supported counterpart.
