When I purchased my ROBO 3D R1+, it came with a black filament guide mounting on top of the printer. It can slide around freely along the top groove. I found it is a nice cool guide that I use it every time I print. Since I have a couple filament spool holders sitting on top of my printer, I decided to print another one so each spool holder would have its designated filament guide.
It should be fairly easy to print, and it prints less than 20 minutes depends on your printer settings.
