Printrbot Simple Metal Filament Tube Guide

This is a remix of the filament guide made by polysign. I have remade the entire model to fit my printer dimension and my 4mm OD teflon tube. You have to print WITH support on this one, and I can't seems to get a smooth finish for the overhang tube as it is too small for the support. I also attached the "blocky" version which doesn't have the overhang cylinder (so no need for support on this one), but looks less elegant :)
