Flashforge Filament routing

I made the spoolholder for https://www.thingiverse.com/thing:2268148 that moved the spools from the back to the front and top. Needed a way to easily route the filament to the extruder so I came up with this.

I added a PTFE tube 10 feet ( 2x5 feet sections ) that is 4mm Inner Diameter and 6mm Outer Diameter to guide the filament. Loading a spool is easy by just pushing filament through until it comes out by the extruder. Works perfect for PLA.

I was planning on putting 2 in the back back corners, but it seemed to sharp a turn. I only ended up using one guide on the side by the back corner.
