Flashforge Creator Pro See Through Filament Guide

thingiverse

Tired of having to glance behind your Flashforge Creator Pro to check the colors of the filaments currently loaded? Well, you're in luck! This solution will allow you to see filament colors while looking at your printer from the front. As a bonus, you'll also get better visual feedback while loading a new filament into the filament guides. To build this solution, all you need to do is obtain a clear PTFE tube with 4mm inner diameter and 6mm outer diameter (sometimes called 4X6mm or just 4X6), cut it with a sharp knife to the same length as the existing tube, and insert it instead. Those clear tubes are available on eBay from several vendors and cost a few bucks. Search for "clear PTFE tube" or something similar. My science-savvy friend informs me that there is no such thing as clear PTFE, and that clear material is probably FEP (Fluorinated Ethylene Propylene). However, my 3D printer doesn't care about the distinction and works just fine.
