Filament Guide for Wanhao i3 (Monoprice Maker Select)

If you positioned your Wanhao control box behind the printer and mounted your spool holder on the control box like I did, this filament guide might prove useful.

It mounts on top of the frame using the already existing screw holes for the spool holder.

Use sufficiently long, looped PTFE tube between this guide and the extruder assembly.

Recommended to use along with http://www.thingiverse.com/thing:877258 mounted on the extruder assembly to hold the other end of the PTFE tube.
