A fairly simple filament guide for Prusa i3 style printer frames. (or anything else that it will fit on.)

There is a 6.4mm slot which gives the filament guide a snug fit onto my Prusa Frame.

The hoop has curved inside edges so the filament can glide through easily.

I wouldn't suggest using it for tall print as the print head may come a bit to close to it..

My first upload woop! Hope its helpful!
