Filament guide for use with a specific filter.

thingiverse

I created this tutorial with a specific objective in mind. I employ a filament filter as described below and also utilize a Teflon tube with an outer diameter of 3mm to ensure my filament remains spotlessly clean and dry at all times. This handy guide prevents the tube from slipping into the filter, thereby allowing it to function precisely as intended. Without this guide, the Teflon tube would slide right into the filter. The filter I utilized can be found here: http://www.thingiverse.com/thing:190118
